DATA FOR CALCULATION OF FLOW 

The coefficient of flow C V 

expresses the rate of flow in gallons per minute at 60ºF water with a pressure drop of 1 psi across 

the valve. The C V 

coefficients for the various types and sizes, shown in the tables, have been determined from actual flow tests. 

Note: K V 

is the metric equivalent of C V 

. (K V 

= C V 

x 0.856

Design Features 

Exceptional Design Features of Spring Pack Loaded(SPL) Parallel Slide Gate Valves 

• KVT Parallel Slide Gate Valves(PSGV) are designed for more reliable sealing tightness and valve operation in fluid flow control. As a 

final control component the reliable tight shutoff function in the valve is one of the most important control factors. 

KVT introduces a long lifetime of the valves with freedom from most problems. Each PSGV in this brochure is based on the 

principles of parallel slide gate design with independent discs; wide flat seats, variable numbers of spring pack to be allowed proper 

sealing forces and a sharp shaped edge on the discs. More than just assuring fluid seating tightness, KVT PSGV design provides 

freedom from sticking or binding results by thermal effects associated with wedge gate valves. 

• No tendency to mark, notch or indent the sealing surfaces, even in presence of girt and positive contacting loads, because parallel 

slide gate valves close with a sliding action, not by compression. This results in better tightness and a longer maintenance free 

lifetime of the discs/seats sealing surfaces. 

• Our, KVT, wide flat seating surface discs with a sharp shape edge have a cleaning action with intimate contact on the seats during 

the closing action. Any polluted impurities on the seats/discs are eliminated and the sealing contact is free from undesirable 

particles. It also reduces seat bearing stress and guarantees long life. The wide flat seating can minimize the effect of minor 

damage to the surface as sealing occurs over the entire surface. 

• Since sealing is obtained by sliding, not by compression, there is no need for final surge of torque to make the seating leak tight. 

No additional power is required for the first effort in unseating the discs. Therefore, actuator size of the parallel slide gate valve can 

be much smaller than the wedge type. Hammering or impacting handwheels are not usually necessary on the parallel slide gate 

valves. 

• Because of the low torque operation, the stress and fatigue on the trim is less on parallel slide gate valves which results in longer 

lifetime and greater leak tight reliability. 

• Since sealing is obtained by sliding, not by compression, the exact position of stem is not critical when the valve is closed. As a 

result, there is no problem with the differences of the thermal expansion coefficient of the materials. Also the actuators can be 

stopped with general position switches. 

• 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 

afterwards. Undesirable malfunction like this never occurs with parallel slide gate valves. 

• In wedge gate valves, the wedge must have positioning guides on its sides to keep it in line while closing under full flow condition. 

These guides are not usually made of any hard material, and tend to wear, and eventually may cause jamming. This never occurs in 

KVT designed parallel slide gate valves, as the disc is guided only by its Stellite Hardfaced sealing surface. 

Another Advantages of SPL Parallel Slide Gate Valve 

The unique SPL(Disc Spring Pack Loaded) gate trim unit comprises all of the operating 

parts of sliding discs. No wedging effects and much smaller contacting stresses on the 

seating mechanism. In high temperature service and high pressure service, the valve is 

never subjected to thermal binding since the SPL gate trim unit absorbs irregular thermal 

expansion due to the structural discontinuity of valve body. 

To avoid the seat wear problems, the disc and seat are hardfaced to keep a different 

hardness with Stellite #12 and Stellite #6 respectively. Remarkable different hardness is 

kept to minimize a galling & its built-up effects on sliding metal surfaces. It results in long 

life cycle of the valve. 

The SPL centralized INCONEL cone springs which distribute uniformly loading on both 

seats as well as compensating for irregular expansion of seats and seat wear. Also the 

precision guiding system in gate trim unit and stem connection eliminate vibration (due 

to flow turbulence) of gate trim unit even the disc position in partially open. KVTs’ SPL 

parallel slide gate valves can be flow throttling in any form of flowing condition.


Operating Tips & Caution 

Operating Tips and Cautions of SPL Parallel Slide Gate Valves 

• Operating Tips for long life service the parallel slide gate valves 

- Operate the valves at least every three months. 

- Keep the stem clean and lubricated (to avoid the corrosion of valves). 

- Inspect the valves regularly per service importance level predefined. 

- Lap seats promptly if the valve leaks. 

- Do not use the hammer blow and/or impacting leverages. 

- Check the packing regularly. 

• General Cautions when operating the parallel slide gate valves 

Since open/close thrust of the parallel slide gate valves is remarkably lower than other types of gate valves, no need to use hammer 

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 

bent when the stopper reaches the yoke pillars. 

In case of electric motor actuated valves, a torque value calculated is only determined to select an appropriate size of motor actuator. 

The limits of stem travel are determined solely by limit switches. Only allows limit switch setting for closed position(sealing position) and 

for open position will be set with torque switch in electric motor actuator. 

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. 

For valves fitted with a bypass, which are electrical actuated, the motor actuated operators shall be sequenced as following cycles, 

- With main and bypass closed, it shall not be possible to open the main valve until the bypass valve has been opened. 

- When main valve has opened fully, the bypass valve shall be closed automatically. 

- With the main valve open, the signal for it to close shall be automatically cause the bypass valve to open. 

- When the main valve reaches the shut position fully, the bypass valve shall be automatically closed and then the cycles will be 

completed. 

For valves fitted with a pressure equalizing valve in addition to the normal bypass valve, the equalizing valve is manually operated and is 

locked in the open position during normal operation. 

• Bypass Valves, Equalizing Valves, and Equalizing Devices Bypass valves are used to reduce the traversing differential pressure across 

the valve seat. This reduces the size of the operating device force, resulting in considerable savings. Also bypass valve provides convenient 

means for the initial warming through pipe line. Equalizing devices are used to relieve the fluid trapped between the seat faces, 

and provide outlet for the fluid displaced by the valve stem traversing to the shut position in non compressible fluid such as boiler feed 

water system. Also the equalizing devices are useful for steam service due to steam condensation. When bypass valve be used, it provides 

a fitting for an equalizing connection from main valve, through the bypass and to the main line. For equalizing inside of the valve 

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 

mounted on bonnet is used to relieve the high pressurized trappings.


Equalizing & By-Passing Device 

WEDGE GATE AND PARALLEL SLIDE GATE 

VALVES FAIL TO OPEN 

Under certain process conditions may be 

attributed to an increase in the required 

unwedging thrust to open the valve due to 

the following phenomena: 

OVER PRESSURIZATION 

May result when liquid, entrapped in 

the center cavity of valves, is heated. 

- The trapped fluid expands and 

the resultant increase in pressure 

may make the valve inoperable. 

In extreme cases, a breach of the 

pressure boundary may occur. 

- Each 1°F rise in temperature 

results in a pressure increase of 

150 psi. 

- Over pressurization may occur 

in both pressure seal and bolted 

bonnet type valves and is not 

restricted to valve size. 

- A length of pipe isolated at both 

ends by a valve may also suffer 

from over pressurization. 

PRESSURE LOCKING 

When P 1 

is significantly larger 

than P a 

or P b 

, pressure locking 

occurs. 

- The potential for pressure 

locking is greater in parallel 

slide valves (double disc 

gate) due to the effective 

area on which the entrapped 

pressure acts. 

THERMAL BINDING 

May occur in wedge type gate valves 

between the wedge and seats due 

to temperature differential between 

inlet and outlet of the valve, when the 

valve was closed hot and the system 

cools down. 

- It may make the valve 

inoperable. 

- The stem expansion and 

other stresses, mechanical or 

thermal, may also contribute as 

valve bodies are not rigid. 

- Thermal binding is more 

common in high temperature 

applications. 

- While wedge type gate valves are 

susceptible to thermal binding, 

parallel slide valves are not.

Operating Tips & Caution 

RECOMMENDATIONS 

1. OVERPRESSURIZATION AND 

PRESSURE LOCKING 

After evaluating and determining that the 

potential for problems exist, the solution for 

over-pressurization and pressure locking 

is to provide pressure relief from the body 

cavity. This can be done in several ways: 

- An internal hole in the disc face (Fig. 7), or in 

the seat (Fig. 8), connecting the body cavity 

to the high pressure side of the valve. The 

valve however will seal only in one direction. 

- An equalizing-pipe and equalizing-valve 

(Fig. 9), connecting the body cavity to 

the high pressure side of the valves, the 

valve must be open to provide relief. 

- Relief valve (Fig. 10 & 11), connecting the 

body cavity to the atmosphere, is another 

way to provide pressure relief, however the 

exhaust from the self-activating type reliefvalve 

must be piped to a safe location. 

Caution must be used when opening 

the drain type relief-valve.

2. THERMAL-BINDING (Fig. 12) 

- Bypass-pipes and a valve will allow warm up 

of both sides of the wedge. (Warm-up lines 

located far away from the valve do not have a 

significant impact on thermal equalization.)

3. COMBINED EFFECTS OF 

OVERPRESSURIZATION PRESSURE LOCKING 

AND THERMAL BINDING (Fig. 13-16) 

When evaluation determines that thermal 

binding may exist in combination with overpressurization 

and/or pressure locking, the 

solution will require combination of both 

equalizing and bypass pipes and valves.

4. OTHER RECOMMENDATIONS 

- Verify the process to see if ∆T between closing and opening 

can be reduced. 

- After closing a wedge type gate valve, back up the stem (1/8” 

to 1/4” turn) to allow room for stem expansion. This is only 

practical in manual valves or electronically controlled motor 

operated valves. 

- Adequate pipe supports can reduce piping stresses. 

- Stroke the valves a few times, immediately after closure, 

if practical, to allow for wedge to warm up, or close valve 

slowly. 

- Under exceptional circumstances for electrically actuated 

valves opt for position seating instead of torque seating on 

closure. This must be discussed with the KVT for warranty 

considerations. 

- Consider the use of parallel slide gate valves, which are not 

subject to thermal binding. It is, however important to realize 

that they are more susceptible to pressure locking, higher 

seat wear, as well as difficulties in positive sealing at low 

pressures. - Contact the KVT for specific design solutions.

Electric Actuators 

Electric Actuators 

In many applications, operation of valves may require the use 

of electric, pneumatic or hydraulic actuators. Such applications 

include those where the valve: 

(1) is too large or has too high a differential shut-off pressure 

for manual operation; 

(2) is not accessible for manual operation; 

(3) is part of a system requiring simultaneous opera-tion of 

many valves; 

(4) must be triggered from a remote location, as is often 

essential for emergency shut-off in hazardous areas. 

We will gladly furnish any type or make of actuator you 

specify, or make recommen-dations for your particular service 

condi-tions. All KVT’s gate, globe and non-return valves can 

be supplied with electric, air, gas or hydraulic driven motor 

actuators or cylinder actuators. 

Motor Actuators 

Motor actuators for moving the stem of the valve can be 

powered by air, gas, hydraulic or electric power. The most 

common method of actuation is the electric motor actuator, 

as it is generally the most cost effective. 

Electric motor actuated vaIves can be provided to meet the 

broadest range of requirements including operating cycle time, 

use of integral or remote controls, starters and indicators, and 

a wide range of power sources. They are less readily adaptable 

to fail-safe operation than cylinder actuators because they 

generally require more stored energy. 

Air motor actuators are often specified in very hazardous 

locations where electric power is not available or permitted. 

The major disadvantage of this type of actuator is air 

consumption, particularly when applied to large valves. The 

combination of high gear ratio and long stroke can drain an 

entire air system unless the air supply system is specially 

designed to accommodate this type of actuator. Like electric 

motor actuators, these are not readily adaptable for a 

fail-safe mode. 

Information Required to Quote Motor Actuators 

1. Valve size, figure number or description. 

2. Valve operating conditions (pressure, temperature, flow rate and fluid). 

3. Maximum differential (shut-off) pressure. 

4. Primary power supply:
