Gate Valve Manufacturers

A gate valve is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The main feature of a gate valve is the sealing surfaces between the gate and seats are planar. The gate faces can form a wedge shape or they can be parallel. Gate valve is sometimes used for regulating flow, but many are not suited for that purpose. Gate valve is characterized as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position. Nonrising stems are used where vertical space is limited or underground.
