0781-3613 - Victor EDGE 2.0 ESS42 Heavy Duty Compressed Air Regulator CGA 346

Victor EDGE 2.0 ESS42 Heavy Duty Air Regulator (CGA 346)

The Victor 0781-3613 (Model ESS42-150-346) represents the second generation of the patented EDGE Series regulators, designed specifically for heavy-duty and high-capacity compressed air applications. This single-stage regulator is engineered to reset the standard for industrial gas control, offering a delivery pressure range of 5 to 150 PSIG. It features a CGA 346 inlet connection, which is the standard for compressed air cylinders in industrial environments, and supports a maximum inlet pressure of 3000 PSIG.

Technically, the ESS42 series is distinguished by its robust internal architecture. The regulator utilizes a stainless steel diaphragm that has been rigorously tested to 50,000 endurance cycles—five times the industry standard. This material choice significantly enhances the regulator's lifespan and ensures consistent flow characteristics over a wide range of cylinder pressures. The diaphragm's resilience is complemented by a robust seat design that provides optimum performance and stability, minimizing pressure fluctuations during operation.

A key innovation in the EDGE 2.0 design is the integration of the SLAM (Shock Limitation and Absorption Mechanism) technology within the adjustment knob. This three-stage crumple system is engineered to absorb the kinetic energy of a falling cylinder, protecting the regulator body and the cylinder valve from catastrophic damage. Furthermore, the regulator incorporates a primary particle trap and a secondary diffuser to minimize contaminant energy reaching the seat, thereby reducing the risk of ignition or failure, although this is more critical in oxygen service, it speaks to the high manufacturing standards applied across the EDGE 2.0 line.

The external design prioritizes usability and safety. The regulator features fully enclosed, highly visible modular gauges protected by a robust metal gauge guard. The delivery gauge is extra-large (2.5 inches / 63.5 mm) with a high-contrast colored face, allowing for precise and easy pressure settings even in low-light conditions. The outlet is positioned at the rear of the regulator and points downward, a strategic design choice that routes hoses away from the operator, reducing tripping hazards and potential snag points. The yellow color-coded knob allows for immediate visual identification of the gas service type (Air), ensuring correct equipment usage in multi-gas environments.
