FE 75/100 Pressure Regulator

The FE75 / FE100 is a two-stage gas pressure regulator by Pietro Fiorentini. 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.

According to the European Standard EN 334, it is classified as Fail Close because it is always supplied with an overpressure protection device (slam shut valve).

The FE75 / FE100 is Hydrogen Ready for NG-H2 blending.
