Wedge Gate Valves

ND100 to ND750

Wedge Gate Valve

A type of gate valve with a wedge shaped gate, which can be raised and lowered vertically to the flow and completely moved out of the flow. This allows little pressure drop in the valve. The gate can be solid or flexible type, the flexible type allowing the wedge to seat properly with an increase in temperature.

Wedge Gate Valves are intended to be used as isolation valves. Sealand often supplies replacement heavy duty wedge gate valves with channel guides and BS10 Table D, E or F flanges for power stations or water/sewage pumping stations
