Straight Through Cast Steel Pressure Seal Gate Valve

Cast Steel Pressure Seal Bonnet Industrial Gate Valve


The flexible wedge is a one-piece, fully guided cast wedge with a central hub to allow the seating faces to move relative to each other, thus compensating for distortion of the body seats due to thermal expansion or piping loads. Seat ring and wedge seating face are set at a 9° angle from vertical to minimize sliding contact of the wedge and seat ring during opening and closing.

Wedging actions help effect a tight seal in low differential pressure services. Flexible wedge construction resists wedge sticking or binding in services where the valve may be closed when cold and opened when hot. Seating surfaces are hardfaced with Stellite®6 to provide high life cycle capability in very high differential pressure services.

The gate is a split design using two discs spring loaded and held together by a gate holder with a corrosion reservior spring to provide initial energizing when closed. The gate relies for seat tightness on the primary fluid pressure acting on the downstream seat. There is no wedging action or extra loading on the seats resulting in considerably lower operating torque. During closing there is a bevel on the bottom of the gate to guide it in between the seats and recompress the spring.


Gate Valve Benefits

  • Little friction and minimal drop in pressure when fully opened
  • Eliminates leaks
  • Rising stem configurations make visual inspections easy
  • Nonrising stem configurations are ideal for areas underground or where space is limited
  • Increase efficiency by saving energy when opening or closing a gate valve
