PF400 Line Pressure Regulators With Vent Limiter
Pietro Fiorentini’s PF400 line of gas regulators are designed to comply with the latest CSA and international standards for regulators suitable for indoor and outdoor installations with no modifications.
The PF400 family of regulators are ideal for a wide range of residential through large industrial applications. The materials and soft parts used in the construction of the PF400 regulators make them suitable for use with natural gas, LPG, Propane air and other non-corrosive gases.
