A check valve or one-way valve is a valve that allows fluid (liquid or gas) to flow through it in only one direction.
Check valve designs have evolved drastically over the last 20 years, and the aim of designers has revolved around increasing the speed of closure under its own power. In the case where pump control valves failure mode is not enough (Or no failure mode at all), a fast acting check valve can provide the solution. Different designs are available, listed below.
