Check Valve

A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications

  • Swing Check Valve
  • Lift Type Check Valves
  • Single Plate Wafer Check Valves
  • Dual Plate Wafer Check Valves

Swing Check Valves

Swing Check Valves is a mechanical device, which normally allows a fluid to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Although these valves are available in a wide range of sizes and costs, many check valves are very small, simple, and/or cheap. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of metal.

An important concept in check valves is the cracking pressure, the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for, and can therefore be specified for a specific cracking pressure.
