Pietro Fiorentini PF80–PF120 Gas Regulator

The Pietro Fiorentini PF80 and PF120 gas regulators are spring-loaded, direct-acting regulators designed for commercial and industrial applications requiring precise low- to medium-pressure natural gas control. Their modular design supports a variety of overpressure protection options, ensuring operational reliability and compliance in a wide range of settings. Built with a balanced valve and internal strainer, these regulators provide stable performance, even under fluctuating inlet pressures.

Whether you're upgrading your gas line system or specifying regulators for a new project, the PF80 and PF120 series are reliable solutions for modern natural gas distribution.
