Wedge Gate Valve
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. Core keywords: bi‑directional sealing, full‑bore isolation, multi‑actuator options, industrial pipeline cut‑off.
FAQ
1
Which stem type should I choose?
Choose rising stem for visible position indication and non-rising stem where installation height is limited.
2
What is the difference between a gate valve and a knife gate valve?
A standard gate valve suits clean liquids; a knife gate valve cuts through solids, slurry and fibres.
3
Can a gate valve regulate flow?
No. Partial opening can cause vibration and seat damage
4
What information is needed for a quotation?
Please provide size, pressure class, medium, temperature, connection, stem type, seat and actuation.
