Line Pressure Regulator Basics

A pressure regulator is a control valve that reduces the input pressure of a fluid or gases to a desired value at its output.

ANSI Z21.80/CSA 6.22 is the standard for line pressure regulators suitable for operation with natural, manufactured, and mixed gases, liquid petroleum gases and LP gas-air mixtures.

Pietro Fiorentini’s GOVERNOR line of gas regulators comply with the latest CSA and international standards for regulators suitable for indoor and outdoor installations with no modifications, which makes them ideal for a wide range of residential through large industrial applications.

Safe, Reliable, and High Performance

Ideal for a wide range of applications, 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.*

  • CSA certified external vent limiter option for indoor installations*
  • Both vertical and horizontal installation positions
  • Complete lockup in absence of gas flow, 100% bubble tight shutoff
  • Designed to be used on furnaces and simple on-off loads
  • PF400 Dual Cut

* As Approved by Local Codes and Standards
