Check Valve

Check Valves are designed so that fluids can flow in only one direction.

These are to be used in medium and high-pressure applications. Check Valves come in quite a lot of designs that include poppet and spring, lift and all other welded high-purity. The excessive flow downstream can easily be stopped, enhancing the system integrity and safety.
