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.
