0780-0806 - Victor SR 710MA-997 Acetylene Manifold Regulator, 2-15 PSIG

Victor SR 710MA-997: High-Flow Precision for Acetylene Manifolds

The Victor 0780-0806 SR 710MA-997 is a specialized single-stage regulator designed for the unique demands of acetylene manifold distribution systems. Engineered for high-flow capacity, this regulator bridges the gap between bulk gas supply and station drops, ensuring consistent pressure delivery across your piping network. With a delivery range of 2-15 PSIG, it is optimized for standard low-pressure acetylene applications, maintaining stability even under varying flow demands.

Robust Construction and Design

At the heart of the SR 710MA-997 is a heavy-duty piston actuation system. Piston regulators are preferred in high-flow and heavy-duty applications for their resilience against pressure spikes and mechanical wear compared to traditional rubber diaphragms. The body and housing cap are machined from solid brass, providing excellent thermal properties and corrosion resistance. The regulator connects to the manifold via a CGA 997 inlet (1"-11 1/2 NPS F), a standard for high-capacity manifold headers.

Performance and Maintenance

This unit is designed for ease of maintenance and long service life. It features a cartridge-type seat assembly with a PCTFE seat material, known for its compressive strength and low deformation. The inclusion of a sintered bronze inlet filter is critical for manifold applications, where pipe scale or debris can be present; this filter protects the seat from scoring and leakage. The regulator also features a Delrin cap bushing for smooth adjustment feel and reduced friction on the adjusting screw. With its high pressure rating capabilities (body rated up to 4000 PSIG, though acetylene service is limited by gas properties) and external relief valve, the SR 710MA-997 stands as a reliable cornerstone for any industrial acetylene manifold system.
