Check valve for gas mixing plants

WEH has developed a new check valve specially designed for mounting into gas mixing plants. It is available for inert or flammable gases and oxygen. The check valve system is designed to minimize the effect of dirt particles on the sealing components within the unit. The check valves are silent in use even under high flow conditions and offer high leak integrity. The check valves are manufactured according to the quality assurance standard ISO 9001 and the pressure equipment directive.
