API6D Parallel Gate Valve


Double Disc Parallel Gate Valve


Rtj Flange Parallel Gate Valve

API6D PARALLEL GATE VALVE Double Disc,SOFT SEAT PTFE, metal to metal ,RTJ flange 


The parallel slide gate valve is designed to avoid any flow turbulence and minimize the pressure drop. It is an
alternative option of double disc valves having single wedge instead of double wedge. The parallel slide gate valve
closes with a sliding action instead of the usual compression, so there is no tendency, notch or indent on the
sealing surfaces. This result of this action can bring a better tightness to the disc on the seat-ring, and a longer
lifetime of the discs and seat sealing surfaces.

    Products Related to Parallel


     trim includes a sliding disc assembly. The absence of a wedging effect significantly reduces the contact

    stresses on the seating mechanism. Thanks to the SPL trim absorbing the inevitable and irregular

    thermal expansion of the valve body, SPL parallel slide gate valves are never subjected to thermal

    binding in high temperature or high pressure services.

    To avoid wear of the valve seats, discs and seats are hardfaced with respectively Stellite #12 and Stellite #6. The resulting hardness difference prevents galling and its built-up effect on sliding metal surfaces,

    thus resulting in long life cycles.

    The SPL centralized Inconel cone springs uniformly distribute the load onto both seats and compensate

    for seat wear and irregular expansion of seats. The precision guiding system in the disc trim and the

    stem connection minimize vibration due to flow turbulence, allowing KVT’s SPL parallel slide gate valves to be made less vulnerable for damages in partly open throttling positions or specific flow conditions.
