Comparison Parallel Slide Gate Valve vs. Wedge Gate Valve

Due to its wide flat seats and position seated design, a parallel slide gate does not require reseating of the disc after a valve closed hot cools down. A double disc wedge gate, due to its torque seated design, may require that you reseat it after cooling due to contraction which may loosen a

A gate valve can be defined as a type of valve that used a gate or wedge type disk and the disk moves perpendicular to flow to start or stop the fluid flow in piping. A gate valve is the most common type of valve that used in any process plant. It is a linear motion valve used to start or stop fluid flow.

Oct 11, 20130183;32;It is also referred to as a slide valve or parallel slide. The disc surfaces are always in contact with the body seats. Like the doubledisc or parallelseated gate valve, its disc seats against the downstream seat, depending on the flow direction. The inside diameter of a conduit gate valve is equal to the inside diameter of the connecting pipe.
