Industrial Check Valve Function and Operation

A check valve is used to allow flow in one direction, but prevent flow in the opposite direction. There are several types of industrial check valves including the piston check, ball check, diaphragm check, wafer check and swing check valves.

They are used in industries such as chemical, petrochemical, pharmaceutical, power, biofuels, food & beverage and water treatment.

They are available with metal-to-metal or soft seats, in sizes from 1/8" NPT to 20" flanged connections, with pressure ratings from full vacuum to 10,000 PSI.

Below is a video courtesy of  Columbia Gorge Community College.  In this video, Instructor Jim Pytel, explains the basic operation of check valves and how they are used in hydraulics.
