0781-1408 - Victor SR4F-580 Heavy Duty High Pressure Inert Gas Regulator, CGA-580

Heavy-Duty Precision for High-Pressure Applications

The Victor SR4F-580 is a heavy-duty, high-capacity single-stage regulator engineered specifically for the rigorous demands of industrial pressure management. Unlike standard regulators that utilize a diaphragm, the SR4F series employs a robust brass piston actuation mechanism. This design choice is critical for applications involving high-pressure switching and dead-end testing, where diaphragm fatigue can lead to premature failure. The machined brass body and housing cap provide a solid foundation, ensuring the unit withstands the physical stresses of heavy industrial environments.

At the heart of this regulator is a cartridge-type seat assembly featuring a PCTFE seat. This material is selected for its excellent chemical resistance and mechanical strength, ensuring a tight, reliable seal even under high-pressure conditions. The regulator is capable of handling a maximum inlet pressure of 3000 PSIG via its CGA-580 connection, making it suitable for a wide range of inert gases including Argon, Nitrogen, and Helium. The delivery pressure range is substantial, offering control from 50 up to 750 PSIG, which is monitored via large, easy-to-read 2.5-inch brass gauges.

Operational smoothness is achieved through the integration of a Delrin cap bushing, which reduces friction during adjustment, allowing operators to dial in precise pressures with ease. Safety is paramount in high-pressure setups, and the SR4F-580 addresses this with an external adjustable relief valve on the F-range model, providing protection against over-pressurization. Additionally, a sintered bronze inlet filter is incorporated to trap particulates, preventing damage to the internal seating surfaces and extending the service life of the regulator.

This unit comes equipped with a 1/4-inch Swagelok outlet connection, facilitating secure and leak-free integration into stainless steel tubing systems often found in testing manifolds and laboratory setups. Whether used for pressure vessel testing or general high-pressure inert gas distribution, the Victor SR4F-580 delivers the reliability and performance professionals expect from the Victor brand.
