Designed for hydrogen applications with up to 1.4 MPa(g) (203 psig) inlet pressure. The H-PCM series electronic Pressure Control Module (PCM) integrates GFI’s Pressure Control Valve (PCV) and Low pressure Isolation Valve (IVL) along with a Pressure Relief Valve (PRV), filter and other customer defined features such as pressure sensor ports.
This system is an electronic pressure regulator that delivers stable outlet pressures under varying fuel cell flow demands and inlet pressures with an integrated low pressure isolation valve.
Each PCM is 100% functionally tested, Helium leak checked and serialized for complete traceability.
