PF400 Standard Model Line Pressure Regulators

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 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.

All PF400 regulators can achieve high outlet pressure accuracy regardless of inlet pressure variation. The external vent limiter reduces piping costs and the need for costly vent piping for indoor installations and complies with CSA guidelines.*

PF400 is suitable for indoor and outdoor*** installation and is Hydrogen Ready for NG-H2 blending.
