0780-0797 - Victor SR700MD-996 High Flow Piston Manifold Regulator

Technical Overview of the Victor SR 700MD-996

The Victor SR 700MD-996 (SKU: 0780-0797) is a heavy-duty, single-stage manifold regulator engineered for high-flow and high-pressure applications. Part of the renowned SR 700 series, this unit is specifically designed to handle the rigorous demands of industrial gas management, including pressure vessel and dead-end testing. The regulator operates via a piston-type actuation mechanism, which offers distinct advantages over diaphragm models in high-pressure environments, providing superior durability and resistance to pressure spikes.

Constructed from a machined brass body and housing cap, the SR 700MD-996 ensures structural integrity and longevity even in harsh operational conditions. The internal architecture features a cartridge-type seat assembly with a PCTFE (Polychlorotrifluoroethylene) seat, known for its high compressive strength, low deformation under load, and excellent chemical resistance. This makes it particularly suitable for managing Air, Oxygen, and Inert Gas services. The unit supports a maximum inlet pressure of 3000 PSIG and provides a delivery pressure range of 5 to 125 PSIG, allowing for precise control across a variety of testing and distribution scenarios.

The inlet connection is specified as a 1"-11 1/2 NPS F manifold connection (referenced as CGA 996 in product specifications), designed to integrate seamlessly into large-scale manifold systems requiring extra high flow capabilities. To ensure operational safety and ease of maintenance, the regulator includes a sintered bronze inlet filter that effectively traps particulates, preventing damage to the seat and piston. Adjustments are smooth and precise thanks to the Delrin cap bushing, and the unit is equipped with 2.5-inch brass gauges that provide clear, immediate visual feedback on system pressure status. External adjustable relief valves are standard on F and G range models, adding an extra layer of safety for over-pressurization events.
