DATA FOR CALCULATION OF FLOW<br />
The coefficient of flow C V<br />
expresses the rate of flow in gallons per minute at 60ºF water with a pressure drop of 1 psi across<br />
the valve. The C V<br />
coefficients for the various types and sizes, shown in the tables, have been determined from actual flow tests.<br />
Note: K V<br />
is the metric equivalent of C V<br />
. (K V<br />
= C V<br />

Design Features<br />
Exceptional Design Features of Spring Pack Loaded(SPL) Parallel Slide Gate <strong>Valves</strong><br />
• KVT Parallel Slide Gate <strong>Valves</strong>(PSGV) are designed for more reliable sealing tightness and valve operation in fluid flow control. As a<br />
final control component the reliable tight shutoff function in the valve is one of the most important control factors.<br />
KVT introduces a long lifetime of the valves with freedom from most problems. Each PSGV in this brochure is based on the<br />
principles of parallel slide gate design with independent discs; wide flat seats, variable numbers of spring pack to be allowed proper<br />
sealing forces and a sharp shaped edge on the discs. More than just assuring fluid seating tightness, KVT PSGV design provides<br />
freedom from sticking or binding results by thermal effects associated with wedge gate valves.<br />
• No tendency to mark, notch or indent the sealing surfaces, even in presence of girt and positive contacting loads, because parallel<br />
slide gate valves close with a sliding action, not by compression. This results in better tightness and a longer maintenance free<br />
lifetime of the discs/seats sealing surfaces.<br />
• Our, KVT, wide flat seating surface discs with a sharp shape edge have a cleaning action with intimate contact on the seats during<br />
the closing action. Any polluted impurities on the seats/discs are eliminated and the sealing contact is free from undesirable<br />
particles. It also reduces seat bearing stress and guarantees long life. The wide flat seating can minimize the effect of minor<br />
damage to the surface as sealing occurs over the entire surface.<br />
• Since sealing is obtained by sliding, not by compression, there is no need for final surge of torque to make the seating leak tight.<br />
No additional power is required for the first effort in unseating the discs. Therefore, actuator size of the parallel slide gate valve can<br />
be much smaller than the wedge type. Hammering or impacting handwheels are not usually necessary on the parallel slide gate<br />
valves.<br />
• Because of the low torque operation, the stress and fatigue on the trim is less on parallel slide gate valves which results in longer<br />
lifetime and greater leak tight reliability.<br />
• Since sealing is obtained by sliding, not by compression, the exact position of stem is not critical when the valve is closed. As a<br />
result, there is no problem with the differences of the thermal expansion coefficient of the materials. Also the actuators can be<br />
stopped with general position switches.<br />
• It is possible that wedge gate valves have a tendency to jam as a result of body contraction, if they are closed while hot, and cooled<br />
afterwards. Undesirable malfunction like this never occurs with parallel slide gate valves.<br />
• In wedge gate valves, the wedge must have positioning guides on its sides to keep it in line while closing under full flow condition.<br />
These guides are not usually made of any hard material, and tend to wear, and eventually may cause jamming. This never occurs in<br />
KVT designed parallel slide gate valves, as the disc is guided only by its Stellite Hardfaced sealing surface.<br />
Another Advantages of SPL Parallel Slide Gate Valve<br />
The unique SPL(Disc Spring Pack Loaded) gate trim unit comprises all of the operating<br />
parts of sliding discs. No wedging effects and much smaller contacting stresses on the<br />
seating mechanism. In high temperature service and high pressure service, the valve is<br />
never subjected to thermal binding since the SPL gate trim unit absorbs irregular thermal<br />
expansion due to the structural discontinuity of valve body.<br />
To avoid the seat wear problems, the disc and seat are hardfaced to keep a different<br />
hardness with Stellite #12 and Stellite #6 respectively. Remarkable different hardness is<br />
kept to minimize a galling & its built-up effects on sliding metal surfaces. It results in long<br />
life cycle of the valve.<br />
The SPL centralized INCONEL cone springs which distribute uniformly loading on both<br />
seats as well as compensating for irregular expansion of seats and seat wear. Also the<br />
precision guiding system in gate trim unit and stem connection eliminate vibration (due<br />
to flow turbulence) of gate trim unit even the disc position in partially open. KVTs’ SPL<br />
parallel slide gate valves can be flow throttling in any form of flowing condition.

Operating Tips & Caution<br />
Operating Tips and Cautions of SPL Parallel Slide Gate <strong>Valves</strong><br />
• Operating Tips for long life service the parallel slide gate valves<br />
- Operate the valves at least every three months.<br />
- Keep the stem clean and lubricated (to avoid the corrosion of valves).<br />
- Inspect the valves regularly per service importance level predefined.<br />
- Lap seats promptly if the valve leaks.<br />
- Do not use the hammer blow and/or impacting leverages.<br />
- Check the packing regularly.<br />
• General Cautions when operating the parallel slide gate valves<br />
Since open/close thrust of the parallel slide gate valves is remarkably lower than other types of gate valves, no need to use hammer<br />
blow hand wheel or big sized hand wheel or impact type leverage. Also do not over torque the stem and watch carefully the stopper not<br />
bent when the stopper reaches the yoke pillars.<br />
In case of electric motor actuated valves, a torque value calculated is only determined to select an appropriate size of motor actuator.<br />
The limits of stem travel are determined solely by limit switches. Only allows limit switch setting for closed position(sealing position) and<br />
for open position will be set with torque switch in electric motor actuator.<br />
At all the times it is never necessary to use extra force at the end of the stroke to make seal for parallel slide gate valves.<br />
For valves fitted with a bypass, which are electrical actuated, the motor actuated operators shall be sequenced as following cycles,<br />
- With main and bypass closed, it shall not be possible to open the main valve until the bypass valve has been opened.<br />
- When main valve has opened fully, the bypass valve shall be closed automatically.<br />
- With the main valve open, the signal for it to close shall be automatically cause the bypass valve to open.<br />
- When the main valve reaches the shut position fully, the bypass valve shall be automatically closed and then the cycles will be<br />
completed.<br />
For valves fitted with a pressure equalizing valve in addition to the normal bypass valve, the equalizing valve is manually operated and is<br />
locked in the open position during normal operation.<br />
• Bypass <strong>Valves</strong>, Equalizing <strong>Valves</strong>, and Equalizing Devices Bypass valves are used to reduce the traversing differential pressure across<br />
the valve seat. This reduces the size of the operating device force, resulting in considerable savings. Also bypass valve provides convenient<br />
means for the initial warming through pipe line. Equalizing devices are used to relieve the fluid trapped between the seat faces,<br />
and provide outlet for the fluid displaced by the valve stem traversing to the shut position in non compressible fluid such as boiler feed<br />
water system. Also the equalizing devices are useful for steam service due to steam condensation. When bypass valve be used, it provides<br />
a fitting for an equalizing connection from main valve, through the bypass and to the main line. For equalizing inside of the valve<br />
a hole(drilled hole in seat or disc) or connecting flow passage on the trim can be used as an equalizing device. Alternatively, relief valve<br />
mounted on bonnet is used to relieve the high pressurized trappings.

Equalizing & By-Passing Device<br />
WEDGE <strong>GATE</strong> AND <strong>PARALLEL</strong> <strong>SLIDE</strong> <strong>GATE</strong><br />
<strong>VALVES</strong> FAIL TO OPEN<br />
Under certain process conditions may be<br />
attributed to an increase in the required<br />
unwedging thrust to open the valve due to<br />
the following phenomena:<br />
OVER PRESSURIZATION<br />
May result when liquid, entrapped in<br />
the center cavity of valves, is heated.<br />
- The trapped fluid expands and<br />
the resultant increase in pressure<br />
may make the valve inoperable.<br />
In extreme cases, a breach of the<br />
pressure boundary may occur.<br />
- Each 1°F rise in temperature<br />
results in a pressure increase of<br />
150 psi.<br />
- Over pressurization may occur<br />
in both pressure seal and bolted<br />
bonnet type valves and is not<br />
restricted to valve size.<br />
- A length of pipe isolated at both<br />
ends by a valve may also suffer<br />
from over pressurization.<br />
PRESSURE LOCKING<br />
When P 1<br />
is significantly larger<br />
than P a<br />
or P b<br />
, pressure locking<br />
occurs.<br />
- The potential for pressure<br />
locking is greater in parallel<br />
slide valves (double disc<br />
gate) due to the effective<br />
area on which the entrapped<br />
pressure acts.<br />
THERMAL BINDING<br />
May occur in wedge type gate valves<br />
between the wedge and seats due<br />
to temperature differential between<br />
inlet and outlet of the valve, when the<br />
valve was closed hot and the system<br />
cools down.<br />
- It may make the valve<br />
inoperable.<br />
- The stem expansion and<br />
other stresses, mechanical or<br />
thermal, may also contribute as<br />
valve bodies are not rigid.<br />
- Thermal binding is more<br />
common in high temperature<br />
applications.<br />
- While wedge type gate valves are<br />
susceptible to thermal binding,<br />
parallel slide valves are not.<br />

Operating Tips & Caution<br />
RECOMMENDATIONS<br />
1. OVERPRESSURIZATION AND<br />
PRESSURE LOCKING<br />
After evaluating and determining that the<br />
potential for problems exist, the solution for<br />
over-pressurization and pressure locking<br />
is to provide pressure relief from the body<br />
cavity. This can be done in several ways:<br />
- An internal hole in the disc face (Fig. 7), or in<br />
the seat (Fig. 8), connecting the body cavity<br />
to the high pressure side of the valve. The<br />
valve however will seal only in one direction.<br />
- An equalizing-pipe and equalizing-valve<br />
(Fig. 9), connecting the body cavity to<br />
the high pressure side of the valves, the<br />
valve must be open to provide relief.<br />
- Relief valve (Fig. 10 & 11), connecting the<br />
body cavity to the atmosphere, is another<br />
way to provide pressure relief, however the<br />
exhaust from the self-activating type reliefvalve<br />
must be piped to a safe location.<br />
Caution must be used when opening<br />
the drain type relief-valve.<br />

2. THERMAL-BINDING (Fig. 12)<br />
- Bypass-pipes and a valve will allow warm up<br />
of both sides of the wedge. (Warm-up lines<br />
located far away from the valve do not have a<br />
significant impact on thermal equalization.)<br />

3. COMBINED EFFECTS OF<br />
OVERPRESSURIZATION PRESSURE LOCKING<br />
AND THERMAL BINDING (Fig. 13-16)<br />
When evaluation determines that thermal<br />
binding may exist in combination with overpressurization<br />
and/or pressure locking, the<br />
solution will require combination of both<br />
equalizing and bypass pipes and valves.<br />

4. OTHER RECOMMENDATIONS<br />
- Verify the process to see if ∆T between closing and opening<br />
can be reduced.<br />
- After closing a wedge type gate valve, back up the stem (1/8”<br />
to 1/4” turn) to allow room for stem expansion. This is only<br />
practical in manual valves or electronically controlled motor<br />
operated valves.<br />
- Adequate pipe supports can reduce piping stresses.<br />
- Stroke the valves a few times, immediately after closure,<br />
if practical, to allow for wedge to warm up, or close valve<br />
slowly.<br />
- Under exceptional circumstances for electrically actuated<br />
valves opt for position seating instead of torque seating on<br />
closure. This must be discussed with the KVT for warranty<br />
considerations.<br />
- Consider the use of parallel slide gate valves, which are not<br />
subject to thermal binding. It is, however important to realize<br />
that they are more susceptible to pressure locking, higher<br />
seat wear, as well as difficulties in positive sealing at low<br />
pressures. - Contact the KVT for specific design solutions.<br />

Electric Actuators<br />
Electric Actuators<br />
In many applications, operation of valves may require the use<br />
of electric, pneumatic or hydraulic actuators. Such applications<br />
include those where the valve:<br />
(1) is too large or has too high a differential shut-off pressure<br />
for manual operation;<br />
(2) is not accessible for manual operation;<br />
(3) is part of a system requiring simultaneous opera-tion of<br />
many valves;<br />
(4) must be triggered from a remote location, as is often<br />
essential for emergency shut-off in hazardous areas.<br />
We will gladly furnish any type or make of actuator you<br />
specify, or make recommen-dations for your particular service<br />
condi-tions. All KVT’s gate, globe and non-return valves can<br />
be supplied with electric, air, gas or hydraulic driven motor<br />
actuators or cylinder actuators.<br />
Motor Actuators<br />
Motor actuators for moving the stem of the valve can be<br />
powered by air, gas, hydraulic or electric power. The most<br />
common method of actuation is the electric motor actuator,<br />
as it is generally the most cost effective.<br />
Electric motor actuated vaIves can be provided to meet the<br />
broadest range of requirements including operating cycle time,<br />
use of integral or remote controls, starters and indicators, and<br />
a wide range of power sources. They are less readily adaptable<br />
to fail-safe operation than cylinder actuators because they<br />
generally require more stored energy.<br />
Air motor actuators are often specified in very hazardous<br />
locations where electric power is not available or permitted.<br />
The major disadvantage of this type of actuator is air<br />
consumption, particularly when applied to large valves. The<br />
combination of high gear ratio and long stroke can drain an<br />
entire air system unless the air supply system is specially<br />
designed to accommodate this type of actuator. Like electric<br />
motor actuators, these are not readily adaptable for a<br />
fail-safe mode.<br />
