Pietro Fiorentini's GOVERNOR gas regulators meet with CSA and international requirements for indoor and outdoor installations. GOVERNOR regulators are appropriate for residential to industrial applications. The GOVERNOR regulators' soft components and materials suit them for natural gas, LPG, Propane air, and other non-corrosive gases. These regulators include balanced valves for superior exit pressure accuracy independent of inlet pressure, with a double diaphragm and vent limiter that adds safety. The outdoor vent limiter saves pipe costs and the need for expensive interior vent piping and conforms with CSA.
Pietro Fiorentini's Goval is a balanced double diaphragm safety governor. It's perfect for burner supply and low-pressure ducted gas distribution, with filtered non-corrosive gases in industrial, commercial, and residential distribution networks.
Norval is a gas pressure regulator by Pietro Fiorentini for medium and low-pressure natural gas distribution networks with filtered gaseous fluids. They are Fail Open per EN 334. Norval is NG-H2-ready.
The pilot-operated Aperval regulates gas pressure. It's ideal for medium and low-pressure natural gas distribution networks and non-corrosive gases. They are Fail Open per EN 334.
Cirval is a gas pressure regulator with a lever-operated diaphragm and setting spring used on medium and low-pressure natural gas distribution networks for commercial and industrial uses. Cirval regulates filtered non-corrosive gases and is Fail Open per EN 334.
