0781-1428 - Victor SR4G-580 High Pressure Piston Regulator, CGA-580, 1500 PSIG Delivery

Heavy-Duty Reliability for Industrial Fabrication

Upgrade your gas regulation equipment with the Victor SR4G-580 Heavy Duty/High Capacity Inert Gas Regulator. Designed for the serious fabricator and industrial maintenance professional, this regulator represents the gold standard in high-pressure gas control. When your operations involve heavy-duty applications such as structural steel fabrication, repair and maintenance, or specialized pressure testing, you need a regulator that won't fail when the pressure is on. The SR4G-580 is that tool.

At the heart of this regulator is its piston-style actuation. While many standard regulators use a diaphragm that can wear out or tear over time, the piston design of the SR4G-580 offers superior durability and is specifically engineered to manage high delivery pressures ranging from 100 up to 1500 PSIG. This makes it an indispensable asset for shops that perform pressure vessel testing or require high-pressure inert gas for specialized processes. The unit connects via a standard CGA-580 inlet, making it compatible with common inert gas cylinders like Argon and Nitrogen.

Durability is woven into every aspect of the SR4G-580's design. The body and housing cap are machined from solid brass, providing excellent resistance to corrosion and physical impact. Inside, a cartridge-type seat assembly with a PCTFE seat ensures a reliable seal that resists degradation from high-velocity gas flow. To further protect your investment, a bronze sintered inlet filter traps dust and debris before they can damage the sensitive internal components. The outlet features a 1/4" Swagelok connection, offering a secure, leak-proof attachment point for high-pressure tubing.

Victor has also prioritized ease of use. The adjustment mechanism features a Delrin cap bushing, which ensures that dialing in your specific pressure requirements is smooth and effortless, preventing the jerky adjustments common in lesser regulators. Equipped with large, 2.5-inch brass gauges, reading your cylinder and delivery pressure is straightforward, even in dimly lit shop environments. Trust in the legacy of Victor equipment to keep your shop running safely and efficiently with the SR4G-580.
