0781-4261 - Victor GT350 Heavy Duty Two-Stage Oxygen Regulator 0-150 PSI

Heavy-Duty Precision with the Victor GT350-150-540

The Victor GT350-150-540 is a premium heavy-duty two-stage regulator designed to meet the rigorous demands of industrial gas regulation. Engineered for Oxygen service, this regulator is a staple in fabrication shops, construction sites, and manufacturing facilities where reliability and safety are paramount. The GT350 series is renowned for its robust construction, featuring a forged brass body and housing cap that can withstand the physical abuse often encountered in heavy industrial environments. Unlike single-stage regulators that may show a rise in delivery pressure as the cylinder pressure decreases, the two-stage mechanism of the GT350 ensures a constant and steady flow of gas throughout the life of the cylinder. This feature is critical for precision cutting and welding applications where flame stability directly impacts work quality.

Advanced Two-Stage Technology

At the heart of the Victor 0781-4261 is its sophisticated two-stage design. The first stage reduces the high pressure from the cylinder (up to 3000 psig) to an intermediate pressure, while the second stage reduces it further to the precise working pressure set by the operator (0-150 psig). This stepped reduction process eliminates the "decay" or pressure fluctuation common in lesser regulators, allowing operators to focus on their weld or cut without constantly tweaking the pressure knob. The regulator is equipped with a CGA 540 inlet connection, making it compatible with standard industrial oxygen cylinders.

Safety and Durability Features

Safety is engineered into every component of the Victor GT350. It features an external self-reseating relief valve on the high-pressure stage, providing a critical safeguard against over-pressurization. The stem-type seat mechanism and Delrin cap bushing ensure smooth operation and longevity, reducing wear on internal components over time. Additionally, a sintered bronze inlet filter acts as a barrier against dirt and debris, preventing contamination that could compromise the regulator's seal or performance. With large, easy-to-read 2.5-inch brass gauges, monitoring cylinder and delivery pressure is straightforward, even in low-light conditions.

Key Industrial Benefits
