Wedge
gate valves are robust isolation valves built for full‑open or full‑closed pipeline cut‑off rather than flow throttling. They deliver bi‑directional tight sealing via wedge‑shaped closure discs, available with metal‑to‑metal or resilient soft seats such as EPDM and NBR. Constructed from cast iron, ductile iron or stainless steel, they support manual handwheel, electric, pneumatic and hydraulic actuation. Complying with AWWA, DIN and BS standards, these low‑flow‑resistance valves suit water, wastewater, irrigation, flood control and power cooling systems, also widely applied in oil‑gas, chemical and mining piping for reliable media shut‑off.
