Victor G350 Series Inert Gas Regulator 0-150 PSI CGA 580

Technical Overview of the Victor G350-150-580 Regulator

The Victor G350-150-580 (SKU: 0781-9416) represents the evolution of medium-duty gas control technology within the renowned G-Series family. Engineered by ESAB/Victor Technologies, this single-stage regulator is specifically calibrated for inert gas applications, including Argon, Nitrogen, and Helium. It features a CGA 580 inlet connection, making it universally compatible with standard inert gas cylinders found in industrial, HVAC, and laboratory environments. The unit provides a delivery pressure range of 0-150 PSIG, suitable for a wide variety of tasks ranging from system purging and blanketing to pressure testing and pneumatic tool operation.

Structurally, the G350 series distinguishes itself from legacy models through material innovation. While the body retains the classic forged brass construction for chemical resistance and mass, the bonnet is manufactured from a high-strength alloy. This design choice significantly increases the yield strength of the bonnet, mitigating the risk of thread damage or deformation if the regulator falls or is subjected to impact—a common failure point in all-brass predecessors. The internal architecture utilizes a stem-type seat mechanism, which provides consistent flow characteristics and reliable shut-off capability.

Operational efficiency is enhanced by the integration of 2-inch (50mm) high-contrast gauges. These gauges feature a polished steel casing and bold graphics, ensuring that inlet and delivery pressures can be monitored accurately from a distance or in low-light conditions. The pressure adjustment knob is color-coded (typically black or specific to the gas service line) and contoured for ergonomic grip, allowing for precise torque application even when the operator is wearing heavy protective gloves. The outlet connection is a standard 5/8"-18 Female (UNF), facilitating easy connection to standard inert gas hoses and fittings.

Safety compliance is central to the G350 design, incorporating an internal relief valve that protects the regulator components from over-pressurization. This unit is an ideal solution for MRO professionals requiring a robust, specification-compliant regulator that bridges the gap between light-duty commercial units and heavy-duty industrial station regulators.
