0781-1448 - Victor SR4J-580 Heavy Duty Piston Regulator, 3000 PSIG Delivery

Heavy-Duty High Pressure Control with Victor SR4J-580

When your project demands high-pressure gas delivery for testing and industrial fabrication, the Victor SR4J-580 High Pressure Inert Gas Regulator is the tool you can trust. Built by ESAB, a leader in welding and cutting equipment, this regulator is designed to handle the tough jobs that standard regulators can't touch. With a delivery range of 200 to 3000 PSIG, it is the perfect solution for pressure vessel testing, dead-end testing, and other high-capacity inert gas applications.

Built Tough for the Jobsite
The SR4J-580 ditches the traditional diaphragm for a rugged brass piston actuation system. This design is far more resilient to pressure spikes and wear, ensuring your regulator performs consistently over time. The body and housing cap are machined from solid brass, providing the structural integrity needed for high-pressure environments. Whether you are working with Nitrogen, Argon, or Helium, the CGA 580 inlet ensures compatibility with standard inert gas cylinders.

Precision and Ease of Use
Adjusting high pressure doesn't have to be a struggle. The SR4J features a Delrin cap bushing that makes dialing in your specific pressure requirements smooth and easy. The large 2.5-inch brass gauges allow you to monitor your tank and line pressure at a glance, keeping your operation safe and efficient. The outlet comes ready with a 1/4-inch Swagelok connection, a gold standard for high-pressure fittings, ensuring you have a secure link to your testing equipment.

Key Features for Welders and Fabricators:

• High Delivery Pressure: Capable of delivering up to 3000 PSIG for specialized testing.
• Piston Design: Superior durability compared to rubber diaphragms in high-pressure service.
• Clean Operation: Sintered bronze inlet filter keeps dirt out of the seat assembly.
• Ready to Connect: Includes 1/4" Swagelok outlet for immediate integration into high-pressure systems.
