0781-0612 - Victor SR 450ME-996 High Capacity Manifold Regulator

Technical Overview of the Victor SR 450ME-996 Regulator

The Victor SR 450ME-996 (SKU: 0781-0612) represents a pinnacle in heavy-duty gas regulation, specifically engineered for high-pressure manifold systems. As part of the renowned SR 450 series, this single-stage regulator utilizes a robust piston-type actuation mechanism rather than a traditional diaphragm. This design choice significantly enhances durability and reliability, particularly when subjecting the unit to the rigors of pressure vessel testing and dead-end testing. The regulator is constructed with a machined brass body and housing cap, ensuring resistance to corrosion and mechanical stress in industrial environments.

Functionally, the SR 450ME-996 is designed to handle a maximum inlet pressure of 3000 PSIG, stepping it down to a precise delivery range of 10 to 200 PSIG. This wide delivery range makes it versatile for various downstream applications requiring stable pressure. The unit features a specialized 1"-11 1/2" NPS F manifold connection (CGA 996), which is critical for integration into large-scale gas distribution systems. The internal cartridge-type seat assembly incorporates a PCTFE seat, a material selected for its excellent chemical resistance and mechanical strength, ensuring a leak-tight seal even under fluctuating pressure conditions.

Operational precision is facilitated by a Delrin cap bushing, which reduces friction and allows for smooth, granular adjustments of the delivery pressure. To protect the sensitive internal components from particulate contamination, the regulator includes a sintered bronze inlet filter. This filtration is essential for maintaining the longevity of the piston and seat assembly. The unit is compatible with a variety of gases, including Air, Oxygen, and Inert Gases, making it a flexible solution for diverse MRO requirements. The inclusion of 2.5-inch brass gauges provides clear, immediate visual feedback on system status, adhering to the high standards expected by industrial safety officers and maintenance engineers.

In summary, the Victor SR 450ME-996 combines heavy-duty materials with precision engineering. Its piston actuation, high flow capabilities, and specific manifold connectivity position it as a critical component for facilities managing bulk gas supply or conducting high-pressure testing protocols.
