0781-5225 - Victor EDGE ETS4-40-350 Two-Stage Hydrogen/Methane Regulator, CGA 350, 2-40 PSIG

Precision Control for Hydrogen and Methane Applications

The Victor EDGE ETS4-40-350 Two-Stage Regulator (SKU: 0781-5225) is a premium industrial gas regulator engineered specifically for Hydrogen and Methane service. Designed to meet the rigorous demands of laboratory, testing, and heavy industrial environments, this regulator features a CGA 350 inlet connection and delivers a precise pressure range of 2-40 PSIG. As a two-stage device, the ETS4 excels in applications where a constant delivery pressure is critical, maintaining a steady flow rate even as the supply cylinder pressure decreases from a maximum of 3000 PSIG.

Advanced Safety and Durability

Safety is paramount when handling flammable gases like hydrogen and methane. The Victor EDGE series incorporates the innovative SLAM (Shock Limitation and Absorption Mechanism) knob. This multi-stage crumple zone technology absorbs impact energy in the event of a cylinder fall, protecting the regulator's vital internal components and the brass adjusting screw. The unit is constructed with a forged brass body and zinc-aluminum housing caps, offering twice the yield strength of traditional brass regulators. Additionally, the gauges are recessed within the body and protected by a high-impact ABS gauge guard, significantly reducing the risk of damage during transport or operation.

Reliable Performance

The ETS4-40-350 is built for consistency. It utilizes a large 2.7-inch fabric-reinforced neoprene diaphragm in the second stage for sensitive pressure control and a 0.75-inch brass piston in the first stage. A sintered nickel-plated bronze inlet filter prevents particulate contamination, extending the service life of the seat mechanism. Whether used for analytical instrumentation or industrial fabrication, this regulator provides the uniform flow performance professionals demand.
