0781-0611 - Victor SR 450 Series Heavy Duty Manifold Regulator CGA 996

Heavy-Duty Manifold Regulation for Industrial Applications

The Victor SR 450MD-996 (0781-0611) is a premium heavy-duty regulator specifically engineered for high-pressure manifold systems. Part of the distinguished SR 450 Series, this single-stage regulator is designed to manage heavy gas flows with precision and reliability. It is particularly well-suited for demanding industrial environments where consistent pressure delivery is critical, such as in pressure vessel testing and dead-end testing applications.

Robust Construction and Design

Durability is at the core of the SR 450MD-996's design. It features a fully machined brass body and housing cap, providing exceptional resistance to physical wear and corrosion. Unlike standard light-duty regulators that use rubber diaphragms, this model utilizes a brass piston-type actuation mechanism. Piston regulators are renowned for their ability to withstand pressure spikes and harsh operating conditions without failure, making this unit a long-lasting investment for your facility. The internal components are further protected by a sintered bronze inlet filter, which prevents particulate matter from damaging the seating surface.

Precision and Performance

The regulator is equipped with a cartridge-type seat assembly featuring a PCTFE seat. This material is chosen for its dimensional stability and resistance to cold flow, ensuring a tight and reliable seal even under high pressure. Adjusting the delivery pressure is effortless thanks to the Delrin cap bushing, which reduces friction for smooth operation. The unit offers a versatile delivery range of 5 to 125 PSIG, accommodating a wide variety of operational requirements. With a maximum inlet pressure rating of 3000 PSIG, it is capable of handling standard high-pressure supply sources safely.

Manifold Compatibility

Distinct from standard cylinder regulators, the SR 450MD-996 is outfitted with a CGA 996 inlet connection (1"-11 1/2" NPS F). This specific fitting is designed for direct integration into gas manifold systems, ensuring a secure and leak-free connection. The regulator is compatible with Air, Oxygen, and Inert Gases, providing flexibility for facilities that manage multiple gas types. Whether used for centralized gas distribution or specialized testing rigs, the Victor SR 450MD-996 delivers the performance professional industries demand.
