Safety shut-off valve Type G PC S 040


In mobile fuel cell applications, a safety shut-off valve for medium pressure ranges is provided for within the storage system.

By means of a patent pilot system, we achieve high flows at very low external and internal leakages. Disrupting shock pressures are avoided by two-stage opening.
