PF Mod. FE
Residential Gas Pressure Regulators

FE is a double-stage self-operated pressure regulator for civil and industrial applications and it is suitable for use with gaseous fluids such as natural gas, LPG and non-corrosive gases.

These regulators are designed to be installed directly on utility meters or on riser mains for civil uses.

They can be installed in any position and in environments or spaces protected against weather. The discharge of the internal relief valve can be conveyed outside in case of installation in closed rooms or underground installations. The regulators are manufactured according to the UNI 8827 standard and the Italian Ministerial Decree dated 16 Apr. 2008; for the classification of the functional performance, reference shall be made to the EN 16129 and EN 334 standards.
