0781-1601 - Victor SR600 Heavy Duty Inert Gas Regulator 0-350 PSI CGA 580

Victor SR600-350-580 Heavy Duty Regulator Overview

The Victor SR600-350-580 (0781-1601) is a premium heavy-duty single-stage regulator engineered for professionals who require reliable pressure control in demanding industrial environments. Part of the distinguished SR 600 series, this regulator is specifically designed for inert gas applications, utilizing a CGA 580 inlet connection suitable for Nitrogen, Argon, and Helium. It provides a substantial delivery pressure range of 0-350 PSIG, making it an excellent choice for high-pressure testing, purging, and blanketing operations where standard regulators may fall short.

At the core of the SR 600's performance is its stainless steel diaphragm. Unlike rubber or neoprene diaphragms found in lighter-duty models, the stainless steel construction offers superior resistance to corrosion and fatigue, ensuring a longer service life and maintaining gas purity. This feature is particularly critical in applications where consistent performance over time is non-negotiable. The regulator also features a stem-type seat mechanism and a sintered bronze inlet filter, which work together to protect the internal components from particulate damage and ensure a tight seal.

Durability is a hallmark of the Victor brand, and the SR600-350-580 is no exception. It boasts a rugged forged brass body and housing cap, capable of withstanding the physical abuse typical of job sites and workshops. The adjustment mechanism is enhanced with a Delrin cap bushing, providing smooth and precise pressure adjustments even under load. Safety is prioritized with an external self-reseating relief valve (not designed to protect downstream equipment, but to protect the regulator itself). The unit is equipped with large, easy-to-read 2.5-inch brass gauges that display both cylinder pressure and delivery pressure clearly.

This regulator is an essential tool for MRO (Maintenance, Repair, and Operations) professionals, fabricators, and technicians involved in HVAC pressure testing or pipeline maintenance. Its robust design and high delivery capacity make it a versatile asset in any industrial gas setup.
