0781-1442 - Victor SR4J-346 High Pressure Air Regulator 200-3000 PSIG

Victor SR4J-346 High Pressure Air Regulator

The Victor SR4J-346 (0781-1442) is a premium heavy-duty high-pressure regulator designed specifically for industrial air applications. Part of the renowned SR 4 series, this regulator is engineered to handle the rigorous demands of high-pressure environments, making it an essential tool for facilities requiring precise pneumatic control. Unlike standard regulators that utilize rubber diaphragms, the SR4J-346 features a brass piston actuation system. This design choice significantly enhances durability and reliability, particularly when subjecting the unit to frequent high-pressure cycling or sudden pressure spikes.

Constructed from a machined brass body and housing cap, the regulator is built to withstand harsh industrial conditions. It features a cartridge-type seat assembly with a PCTFE seat, known for its excellent mechanical properties and resistance to deformation under load. The inclusion of a Delrin cap bushing ensures that adjustments remain smooth and precise, allowing operators to dial in the exact pressure required for their specific tasks. A sintered bronze inlet filter is integrated into the design to trap particulates, preventing damage to the internal seating surfaces and extending the service life of the unit.

This model is configured with a CGA 346 inlet connection, the standard for high-pressure air cylinders, and delivers a pressure range of 200 to 3000 PSIG. The outlet is equipped with a 1/4" Swagelok connection with a stainless steel tube fitting, facilitating secure and leak-free integration into testing rigs and piping systems. Whether used for maintenance, repair, or operations, the Victor SR4J-346 provides the safety and performance professionals trust.
