Check valve:
Check valve: There are three types of Check Valves:A. Swing check valve B. Piston check valve C. Lift check valve

It is used to prevent flow reversal. Fluid pressure keeps the valve open. It is closed either by back pressure of fluid or by weight of the check system.

A. Swing check valve: is used for low fluid velocities and where flow reversal is not frequent. Swing check valve can be used on the discharge side of pressure relief valve.

B. In lift check valve: a disc, piston or a ball is used as a checking device. It can be installed in horizontal or vertical position. The fluid pressure raises or closes the disc or ball. Lift check valves are suitable where pressure drops are high. It is suitable for small pipelines.

C. Piston check valve: is stem operated. It can be operated manually or by a motor. Check valves are available in sizes ranging from 6mm to 600 mm. They can be used for pressures upto 170 kg/cm2 and temperatures upto 675°C. Material of construction for check valve can be cast iron, steel, ductile iron, and corrosion resistant alloys.
