Pressure Seal Gate Valve
Cast steel pressure seal gate valves in butt-weld and flanged end connections — for high-pressure, high-temperature power and process service. Size range 2″ to 24″, pressure class 600–2500. Flexible wedge is a one-piece fully guided cast wedge with central hub that compensates body-seat distortion from thermal expansion or piping loads.





Design Features
- Pressure-seal bonnet — sealing improves with pressure
- Flexible wedge or parallel slide design
- Wedge/seat faces at 9° to minimise sliding contact
- Tight seal in low differential-pressure service
- Resists wedge sticking when valve closes cold and opens hot
- Butt-weld or flanged ends
