0781-1430 - Victor SR4G-680 High Pressure Inert Gas Piston Regulator, 100-1500 PSIG

Victor SR4G-680 High Pressure Inert Gas Regulator

The Victor SR4G-680 (0781-1430) is a premium heavy-duty piston regulator designed specifically for high-pressure inert gas applications. Engineered for precision and durability, this regulator is an essential tool for professionals engaged in pressure vessel testing, dead-end testing, and other industrial processes requiring substantial delivery pressures. With a robust machined brass body and housing cap, the SR4G-680 is built to withstand the rigors of demanding work environments while maintaining exceptional performance standards.

At the core of this regulator is a reliable brass piston actuation system, which offers superior durability compared to diaphragm designs in high-pressure scenarios. The assembly features a cartridge-type seat with a PCTFE seat material, ensuring a tight seal and long service life. Adjustments are made smooth and precise thanks to the Delrin cap bushing, allowing operators to fine-tune delivery pressure with ease. The unit is equipped with 2.5-inch brass gauges that provide clear, accurate readings of both cylinder and delivery pressures.

Safety and longevity are paramount in the design of the Victor 0781-1430. It includes a sintered bronze inlet filter that prevents particulate matter from entering the regulator, protecting internal components from damage. Additionally, an external adjustable relief valve provides an extra layer of safety during operation. With a maximum inlet pressure capability of 5500 PSIG and a delivery range of 100 to 1500 PSIG, this regulator is perfectly suited for handling high-pressure cylinders equipped with CGA 680 connections.
