WEH® Check Valve TVR9 H2 70 MPa
With the TVR9 H2 70 MPa WEH offers a high-performance check valve for use in hydrogen road vehicles or hydrogen fueling stations of the latest generation.
The WEH® TVR9 H2 70 MPa check valves provide a reliable function wherever hydrogen should only flow in one direction within a pipe system and must be prevented from a return flow.
The sealings in the valve are arranged to prevent them from being damaged by dirt particles in the gas flow. The WEH® TVR9 H2 70 MPa Check valve is made of corrosion-resistant stainless steel achieving a very durable unit due to its robust internal structure
