Fiorentini 31053-3BS

Fiorentini 31053-3BS is a rugged 1-inch balanced valve engineered for precise control in gas and fluid systems. This model combines a 4-inch diaphragm with full lockup and internal sensing to deliver reliable shutoff and fast response. A 1/4-inch vent supports safe venting, while the black spring (6-14") provides stable actuation across operating ranges. With MAOP 2 PSIG and included vent protector, it is ready for demanding installations. It carries CSA Z21.18 & Z21.80 certifications and replaces the older 30053-B model for seamless compatibility.
