0781-1405 - Victor SR 4F-540 High Pressure Oxygen Piston Regulator 30-750 PSIG

Victor SR 4F-540 High Pressure Oxygen Regulator (0781-1405)

When your work demands high-pressure oxygen delivery with unwavering reliability, the Victor SR 4F-540 High Pressure Piston Regulator is the tool you can trust. Designed for heavy-duty applications, this regulator is a powerhouse in the Victor SR 4 Series, specifically engineered to handle delivery pressures up to 750 PSIG. It is the ideal choice for professionals engaged in pressure vessel testing, dead-end testing, and other industrial processes requiring substantial oxygen pressure.

Built for the Toughest Jobs
The SR 4F-540 stands out with its piston-type actuation system. Unlike diaphragm regulators that can be sensitive to high-pressure spikes, the brass piston design offers rugged durability and consistent performance under stress. The body and housing cap are machined from solid brass, ensuring the unit can survive the harsh conditions of industrial environments. Inside, a cartridge-type seat assembly with a PCTFE seat ensures a reliable seal, while a sintered bronze inlet filter keeps contaminants out, protecting your investment.

Precision and Ease of Use
Adjusting high pressure shouldn't be a struggle. Victor has equipped this model with a Delrin cap bushing, which provides a smooth, low-friction feel when dialing in your specific pressure requirements. The large, easy-to-read 2.5-inch brass gauges give you instant visual confirmation of your tank and line pressure, helping you maintain safety and efficiency on the job site. The regulator connects easily to standard oxygen tanks via a CGA 540 connection and features a high-quality 1/4-inch Swagelok outlet for secure line attachment.

Safety First
Victor doesn't compromise on safety. The SR 4F-540 includes an external adjustable relief valve, providing critical protection against over-pressurization. With a maximum inlet pressure rating of 3000 PSIG, this regulator is ready to handle standard high-pressure oxygen cylinders with ease. Upgrade your gas control equipment with the Victor SR 4F-540 and experience the difference that professional-grade quality makes in your high-pressure testing and fabrication operations.
