FE

The FE is a two-stage gas pressure regulator for low pressure equipped with integrated slam shut (OPSO), and optional excess flow valve (EFV) which enable UPSO and fire protection valve. It is particularly suitable for low pressure natural gas distribution networks for residential and commercial users. It should be used with previously filtered non-corrosive gases including biomethane and natural gas blended with hydrogen.

FE is Hydrogen Ready for NG-H₂ blending.
