Description

Two-stage direct-operated gas pressure regulator by Pietro Fiorentini, Mod. FE is equipped with integrated slam shut for maximum downstream pressure and the option of slam shut for minimum downstream pressure and excess flow.

Particularly suitable for low pressure natural gas distribution networks for residential users, it can be used with previously filtered non-corrosive gases.

Mod. FE is Hydrogen Ready for NG-H2 blending.
