0781-1444 - Victor SR4J-350 Piston Regulator for Methane/Hydrogen

Heavy-Duty Control for High Pressure Applications

When your work involves pressure vessel testing or dead-end testing with Methane or Hydrogen, you need a regulator that doesn't just handle the pressure—it masters it. The Victor SR4J-350 High Pressure Piston Regulator is built for exactly these kinds of tough, high-stakes jobs. Forget about flimsy components; this beast features a solid machined brass body and housing cap that screams durability. It is designed to take the abuse of the shop or field while delivering consistent performance day in and day out.

The core of this regulator's power lies in its piston actuation. While diaphragm regulators are great for lower pressures, the brass piston design of the SR4J-350 allows it to deliver massive pressures—anywhere from 200 up to 3000 PSIG—without breaking a sweat. This makes it an indispensable tool for testing applications where high pressure is a requirement, not an option. Adjusting that pressure is surprisingly smooth, thanks to the Delrin cap bushing that prevents binding and allows for fine-tuning, so you get exactly the output you need.

Safety and longevity are built right in. The regulator uses a PCTFE seat within a cartridge-style assembly, chosen specifically for its ability to hold up under high-pressure conditions. A sintered bronze filter at the inlet acts as the first line of defense, catching dirt and debris before they can cause internal damage. The unit comes ready to work with a CGA 350 connection for Methane and Hydrogen bottles and features a high-quality 1/4" Swagelok outlet to ensure your setup is secure. If you are working with high-pressure gases, trust the Victor SR4J-350 to keep you safe and productive.
