Fiorentini 31052-2BS Balanced Valve

The Fiorentini 31052-2BS is a 3/4" balanced valve built for high-reliability shutoff in gas or water systems. With a 4" diaphragm and full lockup, it ensures stable operation and precise control, aided by internal sensing for accurate status reporting. The compact design fits tight installation spaces, while robust construction protects against pressure surges and environmental exposure.

This valve carries CSA Z21.18 & Z21.80 certification and is designed to replace 30052-B, delivering rugged performance in demanding environments. The 2 Psig Maop rating provides clear operating limits, and the 1/4" vent supports controlled depressurization during service. A durable black spring, rated for 6-14", ensures reliable actuation across temperatures and cycles.

Engineered for quick integration into plumbing and gas systems, the Fiorentini 31052-2BS combines safety, efficiency, and long service life. The internal sensing eliminates guesswork by providing real-time feedback at a glance, while the diaphragm-driven design minimizes wear. This model is ideal for retrofit projects or new installations that require certified protection and dependable performance.
