0781-1458 - Victor SR4MJ-996 Heavy Duty High Pressure Manifold Regulator, 200-3000 PSIG

Victor SR4MJ-996 High Pressure Manifold Regulator Overview

The Victor SR4MJ-996 (0781-1458) is a premium heavy-duty high-pressure manifold regulator designed to meet the rigorous demands of industrial gas management. Engineered for precision and durability, this regulator is specifically tailored for applications involving inert gases where high delivery pressures are required. With a delivery range of 200 to 3000 PSIG, it provides the versatility needed for pressure vessel testing, dead-end testing, and high-pressure manifold systems. The unit is built to handle a maximum inlet pressure of 5500 PSIG, making it a robust solution for high-capacity gas cylinders and supply systems.

At the core of the SR4MJ-996 is a machined brass body and housing cap, ensuring structural integrity and resistance to the wear and tear typical of industrial environments. Unlike standard diaphragm regulators, this model utilizes a piston-type actuation mechanism. Piston regulators are renowned for their ability to handle higher inlet pressures and provide stable output in heavy-duty applications. The internal components are equally robust, featuring a cartridge-type seat assembly with a PCTFE seat. This material choice offers excellent chemical resistance and mechanical strength, ensuring a tight seal and long operational life even under high-pressure conditions.

Ease of use and maintenance are key features of the Victor SR4MJ series. The regulator includes a Delrin cap bushing which facilitates smooth adjustments, allowing operators to dial in the exact pressure required without binding or stiffness. For protection against contamination, a sintered bronze inlet filter is integrated into the design, preventing particulate matter from entering the regulator and damaging the seat or piston. The unit comes equipped with 2.5-inch brass gauges that provide clear, easy-to-read monitoring of system pressures. The inlet connection is a CGA 996 (1" - 11.5 M NPS), and the outlet is a 1" - 11.5 F NPS, ensuring compatibility with standard high-pressure manifold setups. Whether you are conducting critical pressure tests or managing a high-flow inert gas supply, the Victor SR4MJ-996 delivers the reliability and performance professionals trust.
