What is a 2 psig line pressure regulator used for?
The Governor 2 PSIG (PFG300) is a Class I line gas pressure regulator for systems with inlet up to 2 psig (138 mbar). It reduces pressure to 2 to 14 inches w.c. (5 to 35 mbar) for residential to large industrial users, upstream of utility meters, burners, unit heaters, generators and boilers. Sizes run from 1/2 to 4 inches with a 500:1 turndown.
What is the difference between ANSI Z21.80 and ANSI Z21.18?
ANSI Z21.80 / CSA 6.22 covers line gas pressure regulators: Class I for inlet up to 2 psig, as on this model, and Class II for inlet up to 10 psig, as on the Governor Dual Cut and Governor OPD. ANSI Z21.18 / CSA 6.3 covers gas appliance pressure regulators, such as Zero Governors USA.
Is the Governor 2 PSIG available outside the USA?
Pietro Fiorentini lists the Governor 2 PSIG in its USA range, certified to CSA / ANSI standards for North American codes. Contact us with your project details and we will confirm availability and whether this certification suits your application.
