VALVES & ACCESSORIES

High Side Controls
270A Float Control
The 270A Series valves are direct feed High Side level controls. Mounted in a
chamber balanced to a vessel, or directly in a sump, a rise in liquid level will open
the orifice and allow the liquid to flow downstream.
These valves have a simple needle and seat construction. The 270A valve has a
single port, but the 270AX and 270AY valves are balanced port valves, allowing
their use with larger orifices and at greater pressure drops across the valve.
These valves are generally applied to refrigeration systems with a fixed charge.
700H Series Pilot Operated Control
270A Application Example
The 700H Series valves are pilot operated by a 275AP pilot float valve that modulates the flow of liquid refrigerant. These valves may
also be applied to controlled pressure receivers, thermosyphon vessels, economizers, and for drainage of condensed vapor in heat
reclaim vessels. These flanged piston-type valves have a manual lifting stem and replaceable PTFE seat disc.
It is necessary to size the internal metering plug and spring for the design criteria to which the 700H valve is to be applied, including
mass flow or tonnage and the inlet and outlet pressures of the valve. The valve is pilot operated by a remote pilot float valve with an
orifice suitably sized for each 700H body size.
The typical application of the 700H Series Pilot Operated Valve
is to maintain a liquid seal in the condenser drain line, or in
a thermosyphon vessel, utilizing a 275AP Pilot Float Valve in
a chamber. The pilot float valve follows the upstream liquid
level.
As the condensing load increases, the 275AP float ball rises,
slowly closing the pilot orifice. This reduces the pressure in
the pilot line to the 700H valve, and pressure on top of the
piston bleeds to the downstream side of the 700H valve. The
balance of forces causes the piston with metering plug to
rise, allowing more liquid to move downstream. Alternately,
as the condensing load decreases, the float ball drops and
opens the pilot orifice, thereby putting higher pressure on
the 700H piston. The 700H valve then modulates toward
reducing the flow.
The pilot line must be ¼” nominal pipe for proper operation
(3/8” OD copper tubing is acceptable for halocarbon
applications). It is imperative to install a pressure gauge in
the pilot line between the bonnet of the 700H valve and the
¼” nominal pipe size hand valve.

Low Side Controls - Direct Acting
101 Series Float Control
The 101 Series valve float ball is linked through a forked lever to act
upon a needle or plunger directly over the orifice controlling the
refrigerant flow. A spring is installed over the needle, working in
opposition to the lever, which supports the weight of the float ball.
The spring pressure can be regulated by an external adjusting stem
to make the float lighter or heavier, causing the liquid level to be
lower or higher to any desired point within the range of the spring.
Turning the adjusting stem counter-clockwise will raise the liquid
level. Total level change, at a particular setting, from a fully closed to
a fully open valve is about 2”.
Unless otherwise stated by the vessel manufacturer, liquid level
set point should typically be 2/3 to 3/4 of vessel diameter for
flooded ammonia chillers and 40% of vessel diameter for flooded
halocarbon chillers. A separating vessel above the chiller is
recommended.
300H Series Float Control
The 300H Series internal mounting fixed level low side float valves
are modulation type liquid level controls, designed primarily for
use with ammonia. The valves incorporate a replaceable cartridge
that contains the working needle and seat. The cartridge can be
removed without pump down of the surge drum or evaporator due
to a secondary shut-off arrangement built into the valve. When used
in halocarbon systems, these valves can be supplied with heavier
float balls.
301E Series Float Control
The 301E Series external mounting fixed level float valves are
modulating liquid level controls. The welded steel chamber has a
Phillips Level Eye for a visual check of the liquid level. The valves
incorporate a replaceable cartridge that contains the working
needle and seat. Pump down of the chamber is required to service
the valve. These valves are for use with unitary surge drums and
evaporators, for intercooler or desuperheater level control, small
ammonia or halocarbon chillers, or other applications requiring
external level control. A remote feed line is required from the
valve outlet to the vessel or evaporator. When used in halocarbon
systems, these valves are equipped with heavier float balls.

Low Side Controls - Pilot Operated
701S Series Low Side Valve
The 701S Series Low side valves are pilot operated valves
which meter the flow of liquid refrigerant to an evaporator or
pressure vessel in response to liquid level requirements. The
701S is controlled by a float valve which responds to changing
requirements, providing a modulating control arrangement.
The 701S valves are flanged and may be supplied with a mating
strainer. A metering plug and spring are selected for specific
operating conditions. A manual opening stem, for raising the
metering plug off the internal port and a replaceable PTFE seat disc
are standard.
In fixed level applications, the 701S is typically controlled by a
301E float valve. The 301E is mounted in a welded steel chamber,
external to the vessel where the level is being controlled. The
chamber is equipped with a Phillips Level Eye for visual indication
of the liquid level. A 300H Series float valve, which mounts internal
to the vessel being controlled, will also serve as a pilot float.
General Application for 701S Series Pilot Operated
Valve with 101 Series Adjustable Level Pilot Float Valve
In adjustable level applications, the 701S is controlled by a 101
float valve. The 101 valve has an adjusting stem which permits
the operator to change the level being controlled in the vessel or
evaporator. This valve is also mounted in a welded steel chamber
external to the vessel, and is equipped with a Level Eye.
The 701S valve is actuated by controlling the pressure above the
internal piston. A drop in liquid level, detected by the pilot valve,
reduces pressure in the pilot line as the pilot orifice opens. This
drop in pressure causes the 701S piston to rise and open slots in
the metering plug. Conversely, a rise in liquid level closes the pilot
float orifice and increases the pressure in the pilot line, moving the
piston and metering plug toward the closed position.
Flow in the pilot line is from the top of the 701S to the pilot float
valve. On a 101 valve, the pilot line must be connected to the port
toward the “tail” of the arrow cast in the 101 valve body. On a 301E
valve, the pilot line may be connected to either of the valve inlet
connections on the sides of the valve body. The pilot line must be
¼” Nominal Pipe for proper operation (3/8” OD copper tubing is
also acceptable for halocarbon applications). See the application
diagrams for valve layouts.

Check Valves
600 Series Check Valve
The 600 Series flanged, in-line disc-type check
valves are spring closing with a light spring. They
may be installed in vertical or horizontal runs.
There is a removable back plate that allows the
valve to be disassembled for maintenance.
The 600D has a metal-to-metal seat. The 600D2
and 600D3 check valves incorporate the Durabla
check valve unit. The 600D Series and ‘S’ suffix
valves require about 2 psi pressure drop to open.
The 600J and 600K Series valves are Teflon seated
valves. When ordered without the ‘S’ suffix,
they are supplied with a light spring with a ¼
psi cracking pressure, making them suitable for
gravity drain lines.
The 600 Series check valves prevent reverse flow
of refrigerant in suction, hot gas and liquid lines.
These valves are suitable for liquid refrigerant
gravity drain applications, pump discharge and
suction. When used for gravity drain, they should
be mounted vertically. These valves are designed
for a 300 psi maximum working pressure. When
used in hot gas defrost applications, they are
installed between the drain pan and the hot gas
inlet to the evaporator. In this manner, the valve
prevents liquid from collecting in the drain pan
coil during normal evaporator operation.
The 600 Series check valves are not particularly
suitable for reciprocating compressor discharge
applications and where flow pulsation sets up a
harmonious frequency to that of the valve.
The 600 Series check valve is normally closed, light
spring actuated. When the refrigerant mass flow
is sufficient to create a pressure drop across the
valve to overcome the force of the closing spring,
the disc is forced away from its seat, permitting
flow. As the mass flow decreases, the pressure drop
across the valve will decrease, and the disc will be
forced back against its seat by the closing spring.

Check Valves
700X Series Check Valve
The 700X Series flanged in-line piston type check valves are spring
closing and can be supplied with a 2, 5, 10, 20, 35, 50, 60, 70 and
90 pound differential spring to suit your application. They have a
manual lifting stem and replaceable PTFE seat disc.
The 700X Series check valves prevent reverse flow of refrigerant
in suction, hot gas and liquid lines. These valves are applicable for
reciprocating compressor discharge line service, refrigerant pump
discharge and suction line service and can be applied as a hot
defrost relief valve. These valves can also be applied as the outlet
check valve for various liquid transfer systems.
The 700X Series check valve is normally closed, spring actuated.
When the refrigerant mass flow is sufficient to create a pressure
drop across the valve to overcome the force of its closing spring, the
disc is forced away from its seat, permitting flow. As the mass flow
decreases, the pressure drop across the disc will decrease and the
disc will be forced back against its seat by the closing spring.

700S Series Check Valve
The 700S Series flanged, piston type, gas pressure powered
valves are normally open by a spring beneath the valve piston.
All are equipped with a Manual Lift Stem with a Seal Cap closure.
The pilot line connection in the bonnet is 1/4” FPT.
The 700S Series valve is designed to be applied as a Suction Stop
Valve in suction lines. It also may be applied to liquid legs and
gas return legs on flooded evaporators and liquid drain lines in
transfer systems. Since the valve is spring opening, no pressure
is required to open the valve. On gravity drain application, flow is
unrestricted.
The 700S valve is a normally open valve. It is closed by gas
pressure from a remote source by energizing a pilot solenoid
valve. The gas enters the valve through the 1/4” FPT connection
in the top of the valve bonnet and acts upon the top of the
piston, forcing the seat disc down on the main valve seat bead,
and stopping the refrigerant flow through the main valve. In
order for the valve to close, the inlet pilot pressure on top of
the piston must be a minimum of 7 psi higher than the inlet
pressure to the valve. For the valve to open, the solenoid in the
remote pilot line must be de-energized. The higher pressure
above the piston vents around the piston and approaches the
lower pressure at the outlet of the valve. The spring under the
piston forces the piston up, opening the valve fully to allow
refrigerant flow.
700XT Series 3-Way Check Valve
The 700XT Series 3-way check valves are flanged in-line piston type
check valves with a replaceable seat disc made from PTFE. They have
a spring beneath the piston that holds the valve in an open position
during normal operation so that no bleed to the downstream side is
necessary to maintain a fully open port.
A line from a high pressure gas source enters the 3-way check valve
through the top bonnet, and is normally closed utilizing a solenoid
valve. When the solenoid valve is opened high pressure gas enters
above the piston and closes the main port. Gas then flows through
the center of the piston to the upstream side of the valve in the
direction opposite to the arrow on the valve body. This will raise the
upstream pressure to the level determined by a regulator installed
in the system. While the main port is closed there is a small bleed
to the downstream side. When the solenoid valve is closed, the
3-way check valve immediately opens and restores full flow in the
direction of the arrow.

3-Way Valves
The 3000N and 3000AN Automatic 3-Way valves are configured
with three external ports. The high pressure port (marked “HP”) is
the inlet for pressurized gas. The low pressure port (marked “LP”)
is the vent port. The center “common” port is open to either the HP
or LP port, depending on the position of the internal pistons, as
described a little below.
The 3-Way valves are typically used on gas-pumped liquid transfer
or recirculating systems. The valve’s common port is connected to
the top of the pumper drum (dump trap). The LP port is connected
to the suction accumulator, above the level of the liquid but below
the suction connection on the accumulator. High pressure gas is fed
to the HP port.
With the 3-Way valve connected as described above and the
solenoid de-energized, the pathway between the common and LP
(vent) ports is held open. This is accomplished by high pressure gas
and an internal spring which hold the smaller (HP) piston closed
against the HP seat. The LP port is open. This “vent” position allows
the pumper drum to vent to the suction accumulator while it fills
with liquid.
When the solenoid is energized, high pressure gas is directed
internally to the space above the larger (LP) piston. This causes the
pistons to move in unison, closing the LP seat and the path between
the LP and common ports while simultaneously opening the HP
seat and the path between the HP and common ports. This is the
“high pressure” position. The high pressure gas now flowing into
the pumper drum through the common port can push the liquid
to another location in the system. Typically, the high pressure gas
should be regulated to 10 to 20 psi above the liquid destination
pressure. This may need to be increased for long pipe distances.
However, unnecessarily high pressure can lead to premature valve
wear.
The 3000N Series valves incorporate a manual opening stem below
the solenoid. When this stem is screwed in completely, the valve
will automatically switch from the vent to the high pressure position
when the solenoid coil is energized. Opening the stem ½-turn will
manually cause the valve to switch from vent to high pressure.

Oil Level Valves
270A
The 270A High Side Float Valve, opening on a rise in level, will
transfer oil from a discharge line oil separator to the crankcase of
the compressor or to an oil reservoir. This valve is used for oil in
ammonia and halocarbon systems. The standard orifice supplied
in the valve is 3/32” and will operate to a pressure drop of 250
psi maximum. The capacity of the valve with oil, when fitted with
the standard 3/32” orifice, is approximately 1-1/2 GPM at 100 psi
pressure drop.

275AF
The 275AF Low Side Float valve can be used to maintain the oil
level in the crankcase of a compressor. For multiple compressor
applications, a 275AF valve should be installed on each compressor.
In this case, feed would be from an oil reservoir at an equal or
greater pressure than the compressor crankcase. If the oil reservoir
is at a pressure equal to the compressor crankcase, it must be
elevated at least two feet above the desired compressor crankcase
oil level so that gravity feed can take place. When the oil reservoir
is at a greater pressure than the crankcase, it may be mounted low.
Consult the table below for the maximum orifice size that can be
used with various reservoir pressures.

Level Eye Sight Glass
Description and Function
The Phillips Level Eye is a reliable, industrial-type sight glass.
The Reflex lens indicates the true level of liquid present without
requiring a second lens. The lens appears dark in the presence
of liquid and clear when liquid is not present. Both Reflex and
clear lenses are suitable for refrigerant vessels such as receivers,
intercoolers, suction accumulators, oil separators, surge drums, oil
pots, columns, and liquid line indicators.
The standard length frost shield allows clear vision with refrigerant
temperatures down to -20°F/-29°C, and a 1” longer frost shield is
available for refrigerant temperatures below -20°F/-29°C. The lowest
temperature the Level Eye is suited for is -60°F/-51°C.
The 1100 Series Level Eye is machined from SA36 material, as
specified in Section VIII, Division I of the ASME Boiler & Pressure
Vessel Code. The housing may be welded directly into ASME Code
vessels. The welding end is dimensioned to a nominal 1-1/2”
IPS schedule 80 pipe. The weld neck or threaded neck is also
dimensioned to a nominal 1-1/2” schedule 80 pipe. All retainers
are annealed 416 stainless steel forgings. Type 304 stainless steel
housings are also available.
The 1101 clear lens and 1101R Reflex lens and are both made
of borosilicate glass. Both are used with a Buna-N gasket on the
inside and a fiber gasket on the outside (between the glass and
the retainer). The maximum temperature differential for the glass
is 477°F; the maximum temperature for the gaskets is 250°F. The
maximum working pressure is 1000 psi.

Filter/Strainer
Phillips offers three styles of compact filters to protect a variety of
refrigeration equipment from particulate matter. The 510 and 575 styles
are angle-type, typically used with low-side float valves. These filters have
FPT connections. The S701JRP is a flanged globe-style filter, typically used
with small piston-type valves. All of these filters feature screen assemblies
that are reinforced with perforated stainless steel sleeves.

Float Switch
Description and Function
The FSP Float Switch is designed to provide an electromechanical
response to liquid refrigerant level changes. This mechanism can be
applied to an operating temperature range of -50°F to +150°F (-45°C to
+65°C).
The zinc plated float chamber has a design working pressure of 400 psig.
The switch is a hermetically sealed 10-amp single-pole, double-throw
switch that is magnetically actuated. It comes with a DIN connector with a
15 foot cable. The piping connections are dual function ¾” FPT or 1” butt
weld. Options include a switch housing heater, a Phillips Level Eye with a
frost shield (Model FSPLE), and a metal cover for the switch housing. The
housing is completely interchangeable with the RS LLSS float switch.
Operation
The float switch is applicable to control liquid refrigerant levels in flooded
evaporators, transfer vessels, high pressure receivers, controlled pressure
receivers, intercoolers, suction accumulators, thermosyphon receivers and
liquid refrigerant recirculating accumulators, and other applications where
level control is required.
The purpose of the FSP float switch is to interact to energize or de-energize
solenoid valves, magnetic starters, operating liquid refrigerant pumps and
plant safety shutdown of compressors. It can also activate safety alarms or
lights for precursory and conclusive high or low liquid levels.
Installation
The float switch should be mounted in a vertical position. Do not trap the
lower balance line on ammonia applications. Service valves should always
be utilized, with stems in the horizontal position. When multiple float
switches are used on a control system, only top and bottom balance line
and valves should be utilized.

Recirculating Injectors
The Phillips Recirculating Injector is a simple device that uses the energy of high-pressure refrigerant to get maximum heat transfer in
an evaporator.
The usual application is the fixed charge type, that is, a single compressor with a single evaporator. Phillips Recirculating Injectors find
their greatest use with ice builders, milk coolers, Baudelot-type chillers, farm tanks, slush freezers, and many types of freezing plates.
The “fixed charge” injector system operates with the entire charge of refrigerant in the evaporator and the surge drum. The condenser or
receiver is always empty except for the refrigerant being condensed and passing through the liquid line to the evaporator.
The Phillips Recirculating Injector uses the energy of the fluid as it expands through the nozzle and acts like a liquid pump, recirculating
the extra liquid from the surge drum through the evaporator and back to the surge drum with the gas evaporated in the tubes or plates.
A liquid indicator should always be installed in the liquid line and will usually show some gas bubbles moving with the liquid during
normal operation. The gas in the liquid line indicates that the condenser is empty, as it should be, with the entire charge in the low
side. A liquid seal in the liquid line, i.e., no gas and all liquid, indicates trouble such as a partially or completely plugged injector nozzle
orifice, a nozzle orifice that is too small for the refrigeration load, or an appreciable refrigerant overcharge.

The recirculation rate is estimated at 2 times the evaporation rate for the selections shown in the tables. The effects of an oversized throat
are an increase in the amount of liquid recirculation and a reduction in the injector discharge head. The reverse applies to an undersized
throat.
The effects of an undersized nozzle are an increase in the amount of liquid recirculation and a decrease in the injector discharge energy.
Avoid under sizing the nozzle, as this reduces the system capacity, raises the head pressure, and causes less oil to be returned.
Injector selection is a three-step process: (1) select the nozzle, (2) select the throat, and (3) select a body style. The following information is
required: Refrigerant type, refrigeration load, suction and condensing temperatures, and degrees of sub-cooling.
Step 1: Nozzle Sizing
First correct the refrigeration capacity for the conditions in tables 1, 2 and 3 (if applicable). Divide the capacity by the factor in Table 1. Do
the same for Tables 2 and 3. Select the nozzle from Table 4 that has a capacity equal to or greater than the adjusted capacity.

Plate and Frame Injector Control
The Phillips injector may be applied to a “fixed” charge system or a “central” type system. Its application with a plate and frame unit allows
for a smaller surge drum, thereby reducing operating cost, first cost, and maintenance cost. The cost savings in a “fixed” charge system are
particularly advantageous because a liquid level control assembly is not required. The liquid level control assembly required for a “central
system” installation may consist of either a Phillips float valve or a float switch with a solenoid valve. Multiple injectors may be employed
to parallel plate and frame applications.
The Phillips injector meters the liquid refrigerant from the system through the nozzle and is mixed with liquid refrigerant from the surge
drum. This mix is introduced through the throat at a recirculated rate into the plates for efficient operation. Sample selections for various
plant sizes and operating conditions follow.
