Wedge Gate Valves
Heavy-duty wedge-gate valves engineered for high-pressure and high-temperature performance, built to API/ASME standards for industrial, oil & gas, LNG, and power applications.
The Wedge Gate Valves are industrial-grade shut-off valves designed for reliable and durable performance under extreme conditions. Built with forged or cast body and bonnet, these valves are available with solid, flexible, or parallel slide wedge designs. They feature an outside screw & yoke arrangement with a non-rotating stem and provide bi-directional sealing.
With full-port flow for minimal pressure drop and metal-seated, hard-faced gates and seats, these valves ensure long-term sealing integrity. They comply with major international standards such as API 600, ASME B16.34, and EN 12516.
Available in a wide range of sizes (2”–48”) and pressure classes (Class 150–4500), these valves can operate in temperatures from –196 °C to 650 °C. Material options include carbon steel, stainless steels, duplex/super-duplex, and nickel-based alloys such as Monel, Inconel, and Hastelloy.
End connections include flanged, buttweld, compact flanges, and hub ends. Valves can be operated manually or fitted with electric, hydraulic, or pneumatic actuators. Optional configurations include cryogenic design, fire-safe design, pressure-seal bonnet, bypass, extended stems, and custom coatings.
