Solid Wedge Gate Valve is manufactured with solid wedge, which has higher strength. Because the wedge is solid, when working, there will be less de-formation happing to the gate, it will have to depend on the stress from the stem to achieve sealing with seat of valve.

GW produces the following gate valves

Solid Wedge Gate Valve OS&Y,

No Rising Stem Solid Wedge Gate Valve

Rubber Wedge Gate Valve

Soft Wedge Gate Valve

Resilient Seated Solid Wedge Gate Valve
