The Victor SR 4PK-250 (0781-1475) is a premium high-pressure regulator designed for demanding industrial applications requiring precise control of specialty gases. Engineered as part of the SR 4 series, this heavy-duty regulator utilizes a piston-type actuation mechanism rather than a traditional diaphragm, making it exceptionally robust and capable of handling high delivery pressures ranging from 300 to 4500 PSIG. The unit is specifically configured for panel mounting, featuring a 5/8" - 20 UNF male inlet connection and a 1/8" F NPT outlet, allowing for seamless integration into gas distribution panels, test benches, and custom manifold systems.
Constructed from machined brass, both the body and housing cap offer superior resistance to wear and corrosion, ensuring a long service life even in rigorous environments. The internal design features a cartridge-type seat assembly with a PCTFE seat, which provides reliable sealing and chemical resistance. To further enhance durability and performance, a sintered bronze inlet filter is incorporated to trap particulates and protect the internal components from damage. The regulator is also equipped with a Delrin cap bushing, which facilitates smooth and precise pressure adjustments, critical for applications such as pressure vessel testing and dead-end testing.
Safety and monitoring are paramount in high-pressure systems. The SR 4PK-250 includes 2.5-inch brass gauges that provide clear, easy-to-read pressure metrics. While designed for high-pressure specialty gas delivery, it is essential to verify gas compatibility; hydrogen models in this series typically feature ventable relief valves, whereas this specific configuration is optimized for general high-pressure utility. Whether used in a laboratory setting, a manufacturing facility, or a testing station, the Victor SR 4PK-250 delivers the reliability and capacity professionals expect from Victor equipment.
