0781-1401 - Victor SR4F-320 Heavy Duty High Pressure CO2 Regulator

Victor SR4F-320 Heavy Duty High Pressure CO2 Regulator

The Victor SR4F-320 (0781-1401) is a premium heavy-duty high-pressure piston regulator designed specifically for Carbon Dioxide (CO2) applications. Engineered for the most demanding industrial environments, this regulator is part of the renowned SR 4 Series, known for its reliability and precision. Unlike standard diaphragm regulators, the SR4F utilizes a brass piston actuation mechanism, which provides superior durability and performance when handling high delivery pressures ranging from 50 to 750 PSIG.

Constructed with a machined brass body and housing cap, the SR4F-320 is built to withstand the rigors of daily industrial use. It features a cartridge-type seat assembly with a PCTFE seat, ensuring a tight seal and long service life. The inclusion of a Delrin cap bushing allows for smooth, low-torque pressure adjustments, giving operators precise control over output. A sintered bronze inlet filter is integrated to trap impurities, protecting the internal components and extending the regulator's operational lifespan.

This model is equipped with a CGA 320 inlet connection, standard for CO2 cylinders, and includes a 5/8"-18 UNF outlet with a 1/4" stainless tube fitting, making it ready for immediate integration into pressure vessel and dead-end testing setups. Safety is paramount, and the SR4F includes an external adjustable relief valve to prevent over-pressurization. With a maximum inlet pressure rating of 3000 PSIG, this regulator is the professional's choice for high-pressure gas control.
