PF FE75 / FE100 Gas Pressure Regulator

The FE75 / FE100 is a two-stage, spring loaded direct acting gas pressure regulator by Pietro Fiorentini. It is particularly suitable for low pressure natural gas distribution systems for residential and commercial users. It should be used with previously filtered noncorrosive gases including biomethane and natural gas blended with hydrogen.

According to the International Standard ISO 23555-2 and European Standard EN 334, it is classified as Fail Close because it is always supplied with an over pressure protection device (slam shut valve). The FE75 / FE100 is Hydrogen Ready for NG-H2 blending.
