Detail / Feature / Application

  • 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. 

  • Check valves are often part of common household items. Although they 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 plastic or metal.
