Victor 0781-1475 Single Stage High Capacity Panel Mount Regulator

Product Description

The VICTOR 0781-1475 is a heavy-duty, single-stage, high-pressure panel mount piston regulator rated for delivery pressures up to 4500 psig. Built around a machined brass body with brass housing cap, it uses a cartridge-type seat assembly with a PCTFE seat and a brass piston with Delrin cap bushing for consistent, smooth outlet pressure adjustment. The inlet connection is 5/8 inch - 20 UNF with a bronze sintered filter, and the outlet is 1/8 inch F NPT. At 3.95 pounds, it is designed for stationary panel-mount installations where high-pressure accuracy and durability are required. Licensed gas equipment technicians and industrial piping professionals are the typical installers.

The 0781-1475 is suited for high-pressure applications where precise delivery pressure and reliable shutoff are critical. Its primary application is pressure vessel and dead-end testing, where outlet pressures approaching 4500 psig must be held without drift. The panel-mount configuration makes it appropriate for fixed test bench and laboratory setups. Brass construction with PCTFE seat material provides broad compatibility across non-corrosive high-pressure gas services. An external adjustable relief valve adds a layer of overpressure protection for the downstream circuit.

Key Features

Compatibility

Designed for panel-mount, single-stage high-pressure regulator applications in pressure vessel testing and dead-end test circuit service. Consult VICTOR documentation to confirm gas service and pressure range compatibility for your specific installation.

Installation Notes

Installation should be performed by a qualified gas equipment technician or industrial piping professional familiar with high-pressure systems. Depressurize and isolate the supply line completely before mounting or servicing this regulator. Verify that all downstream components are rated for the maximum delivery pressure of 4500 psig before commissioning. Follow applicable facility safety codes and manufacturer guidelines when configuring the external relief valve setpoint.
