0781-4255 - Victor GT350 Two-Stage Industrial Air Regulator CGA 346

Victor GT350-150-346 Heavy Duty Two-Stage Air Regulator

The Victor GT350-150-346 (SKU: 0781-4255) is a premium heavy-duty two-stage regulator designed specifically for Industrial Air applications. Engineered for environments requiring precise and constant delivery pressure, this regulator excels where inlet pressures fluctuate as the cylinder empties. The two-stage mechanism reduces the cylinder pressure in two steps, ensuring that the working pressure remains stable throughout the life of the cylinder, a critical feature for sensitive pneumatic tools and industrial processes.

Constructed with a forged brass body and housing cap, the GT350 series is built to withstand the rigors of harsh industrial environments. It features a CGA 346 inlet connection, which is the standard designated fitting for industrial air cylinders up to 3000 PSIG. The regulator offers a delivery pressure range of 5 to 150 PSIG, making it versatile for a wide variety of applications. Key structural components include a Delrin cap bushing for smooth pressure adjustment and a stem-type seat mechanism that enhances reliability and service life.

Safety and ease of use are paramount in the GT350 design. It is equipped with an external self-reseating relief valve (not designed to protect downstream equipment, but to protect the regulator itself) and a sintered bronze inlet filter to prevent particulate contamination. The large 2-inch gauges provide clear visibility of both cylinder and delivery pressures, ensuring operators can monitor system status at a glance. This regulator represents the gold standard in gas control for professionals demanding durability and precision.
