The FE is a two-stage gas pressure regulator by Pietro Fiorentini. There are two types of the regulator:
- FE 25 (875 cfh) / FE 50 (1,500 cfh) lever-operated
- FE 75 (2,600 cfh) / FE 100 (3,500 cfh) spring loaded
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 FE is Hydrogen Ready for NG-H2 blending.
The balanced 1st stage regulation limits the pressure variation to the 2nd stage, so it is possible to reach high accuracy of the regulated outlet pressure. Therefore, a balanced double stage regulator has a single-size orifice for all pressure and flow conditions.
The FE can be installed in vertical or horizontal position. For FE 25/FE 50: one in-line or 90° inlet and two outlets. For FE 75/FE100: one in-line inlet and two outlets. This reduces greatly space requirements for all types of installations.
The FE regulator is highly customizable in terms of settings, fittings and accessories.
