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

Reliable Inert Gas Control for Testing and Manifolds

For welders and fabricators requiring high-pressure inert gas control, the Victor SR4F-580 offers a level of ruggedness and precision that standard regulators cannot match. Built on the legendary Victor SR 4 platform, this regulator is designed to handle the tough jobs where delivery pressures need to reach up to 750 PSIG. It is the ideal choice for specialized tasks such as pressure vessel testing, dead-end testing, and high-pressure manifold applications where consistency and safety are non-negotiable.

The defining feature of the SR4F-580 is its piston-style actuation. In high-pressure scenarios, rubber diaphragms can be a weak point, susceptible to rupture or wear. By utilizing a solid brass piston, Victor ensures that this regulator can withstand sudden pressure spikes and continuous high-pressure use without compromising performance. This durability is complemented by a heavy-duty machined brass body that resists corrosion and physical impact, making it suitable for shop and field environments alike.

Adjusting the pressure is smooth and predictable, thanks to the Delrin cap bushing that prevents binding in the adjustment screw. This allows for fine-tuning of the delivery pressure anywhere between 50 and 750 PSIG. The regulator connects to standard inert gas cylinders via a CGA-580 inlet and features a professional-grade 1/4-inch Swagelok female outlet, ready for high-pressure tubing connections. The included 2.5-inch brass gauges provide clear visibility of both cylinder contents and delivery pressure.

Maintenance and longevity are also key aspects of the design. The cartridge-type seat assembly allows for easier serviceability, while the sintered bronze inlet filter acts as a first line of defense against tank debris. With its external adjustable relief valve, you can operate with confidence knowing there is a built-in safety mechanism. When your project demands high-pressure inert gas delivery with industrial-grade reliability, the Victor SR4F-580 is the tool for the job.
