Frequently asked questions

What does a zero governor do?

A zero governor keeps the pressure downstream of the regulator at zero, adjustable from -5 to +5 mbar, for gas appliances and burner feeding. Pietro Fiorentini Zero Governors are double diaphragm safety governors with a balanced plug, for inlet up to 350 mbar, in sizes from 1/2 to 4 inches, and comply with EN 88-1.

Is a filter included with the Zero Governors?

An integrated inlet filter is optional, and inlet and outlet pressure ports are available. Minimum differential pressure is 20 mbar and the operating temperature range is -10 to +60 °C. For North American projects that need ANSI Z21.18 / CSA 6.3 certification, Zero Governors USA (PFG300-ZE) is the matching model.

Do you supply Zero Governors in Saudi Arabia and the GCC?

Yes. Our Al Khobar team supplies and supports the Zero Governors for burner and appliance projects in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Contact us with the size, inlet pressure and burner data for a quotation.
