FLOW
Parallel slide construction can be furnished for high differential pressure services or where thermal expansion may cause sticking of a wedge type.
The parallel slide gate assembly consists of two interchangeable spring loaded discs, a fully guided disc holder, and retaining pins.
Springs are fitted between discs to provide initial sealing force only, and do not maintain the sealing force.
Discs are interchangeable which simplifies in-line maintenance and eliminates the need to custom fit the seats to the discs.
Position seating eliminates stress and potential binding due to thermal expansion of the stem.
No additional torque required to achieve a positive seal once disc are in position.
Lower seating torque to reduce actuator size and cost
Hardfaced seating surfaces provide high cycle capability in very high differential pressure services
By-pass valve are used to reduce the traversing differential pressure across the valve seat.It reduces the size of the operating gear and also provide a convenient means for the initial warming through of pipe lines
Equalizing devices are used to relieve the fluid trapped between the seat forces, and to provide an outlet for the fluid displaced by the valve stem traversing to the shut position.
