Wedge gate valve is one of the most common gate valves, is a valve which uses the up and down operation of the gate to open and close the fluid medium in the pipe. The flexible wedge gate valve is a single piece, optimized large bore gate valve with body guided, split wedges, offering superior leak tightness and performance. It is named because the sealing surface is wedged with the vertical center line at an Angle. Wedge gate valve is generally used where need not strict requirements about size or harsh conditions such as high temperature and high pressure of the working medium or the closure of the need for long-term sealing.
