PF Zero/Ratio GOVERNOR Regulators

Pietro Fiorentini’s Zero/Ratio GOVERNOR is designed to comply with the ANSI Z21.80 standard.

The Zero/Ratio family of regulators are ideal for all burner installations, nozzle mixers, mixing tees, and proportional pre-mixers. Their function is to regulate the pressure and to maintain constant the air/gas ratio.

The materials and soft parts used in the construction of the Zero/Ratio GOVERNOR regulators make them suitable for use with natural gas, LPG, city gas and all other non corrosive gases.

All the PF Zero/Ratio GOVERNOR regulators are equipped with balanced device design for high outlet pressure accuracy regardless of any inlet pressure variation. The double diaphragm provides added security in case of primary diaphragm failure.
