Victor 0781-1453 Single Stage High Pressure Inert Gas Regulator

Product Description

The VICTOR 0781-1453 is a heavy-duty, single-stage, high-pressure inert gas piston regulator built for demanding industrial applications. It delivers an adjustable outlet pressure range of 200 to 3000 psig and accepts inlet pressures up to 7500 psig. The body is machined brass with a matching brass housing cap. A cartridge-type seat assembly with a PCTFE seat provides reliable sealing and long service life. The Delrin cap bushing on the piston actuator ensures smooth, consistent pressure adjustments. Licensed gas technicians and industrial service professionals install and service this regulator.

This regulator is engineered for pressure vessel testing and dead-end pressure testing applications where stable, high-pressure inert gas delivery is required. It accepts a 677 CGA inlet connection fitted with a bronze sintered inlet filter to protect internal components from particulate contamination. The outlet is a 1/4-inch Swagelok connection with a 1/4-inch stainless tube fitting. An external adjustable relief valve provides overpressure protection. The two 2.5-inch brass gauges give clear inlet and outlet pressure readings at a glance.

Key Features

Compatibility

Designed for single-stage pressure regulation of inert gases in high-pressure industrial systems requiring a 677 CGA inlet connection and 1/4-inch Swagelok outlet, with inlet pressures up to 7500 psig.

Installation Notes

Installation should be performed by a qualified gas technician familiar with high-pressure gas systems and applicable codes. Depressurize and isolate the gas supply completely before connecting or disconnecting this regulator. Verify that the CGA inlet fitting and outlet connection are properly torqued and leak-tested with an appropriate leak detection solution before returning the system to service. Never exceed the rated maximum inlet pressure of 7500 psig.
