Pietro Fiorentini Trias Regulator

The Pietro Fiorentini Trias is a compact, direct-acting gas pressure regulator designed for low- and medium-pressure applications. Controlled by a diaphragm and counter spring, the Trias regulator delivers accurate, consistent performance even in fluctuating conditions.

With its balanced valve design, the Trias ensures high outlet pressure stability regardless of inlet variations. It is ideal for non-corrosive, filtered gas and offers top-entry access for simplified maintenance without pipeline disassembly.
