A Gate Valve is a valve which opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can be parallel, but are most commonly wedge-shaped.Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.

A Globe Valve is used to regulate flow by a movable plug and stationary seat which separate two internal chambers. The plug can be screwed in to close the valve against the seat. Globe valves are used for applications where throttling or repeated operation is required. They can provide fine control of flow and are the most common type of valve to use for modulating flow.

A check valve is used to allow fluid flow in a system in only one direction. They are operated by the flow of fluid in the piping. A check valve may be the swing type, lift type, or ball type. Most valves can be classified as being either stop valves or check valves. Some valves, however, function either as stop valves or as check valves-depending on the position of the valve stem. These valves are known as stop-check valves. China Cast Steel Swing Check Valve Manufacturer Provider Supplier BS1868 Swing Check Valves
