Check Valves

Valves

Check valves are designed to stop the flow in one direction and have unrestricted flow in the opposite direction. Typically a check valve has a spring-preloaded ball or a plunger pressing on the seat. The seat conforms to the plug, and has a through-hole such as an orifice to allow the pressure from the opposite side of the plug overcoming the spring preloading force. Check valves designated for applications in ultra high purity, UHP are typically used in photonics, semiconductor fabs or bio-pharma.
