Victor 0781-1442 High Pressure Gas Regulator

Product Description

The VICTOR 0781-1442 is a heavy-duty, high-pressure piston-type gas regulator designed for demanding industrial and trade applications. Built with a machined brass body and housing cap, this regulator delivers controlled outlet pressure for methane and hydrogen gas service. A cartridge-type seat assembly with PCTFE seat provides reliable shutoff and seating performance. The piston-type actuation mechanism is brass construction, and a Delrin cap bushing allows smooth, precise pressure adjustments. Delivery pressures reach up to 4500 PSIG on applicable models. Licensed gas technicians and industrial service professionals are the primary installers of this regulator.

The VICTOR 0781-1442 is ideally suited for pressure vessel testing and dead-end testing applications where high-pressure gas delivery accuracy is critical. It is designed for use with methane and hydrogen gas. F and G range models include external adjustable relief valves. Hydrogen models feature ventable relief valves, while J Series models do not include venting. The sintered bronze inlet filter protects internal components from particulate contamination common in high-pressure cylinder supply lines.

Installation Notes

Installation should be performed by a qualified gas technician or licensed professional familiar with high-pressure gas regulator service. Shut off the cylinder valve and relieve all system pressure before connecting or disconnecting this regulator. Verify that all fittings and connections meet applicable code requirements for the gas type being used. Inspect the inlet filter and seat assembly during installation and do not over-tighten inlet connections to avoid thread or seat damage.
