0781-5226 - Victor EDGE ETS4-125-350 Two-Stage Hydrogen/Methane Regulator

Victor EDGE ETS4-125-350 High Capacity Two-Stage Regulator

The Victor 0781-5226 EDGE ETS4-125-350 is a premium high-capacity, two-stage regulator designed specifically for Hydrogen and Methane gas applications. Engineered for environments where precise and constant outlet pressure is critical, this regulator maintains a steady 5-125 PSIG delivery range even as the cylinder pressure decreases. This makes it an ideal choice for laboratory testing, industrial manufacturing, and specialized welding applications where consistency is paramount.

Safety and durability are at the core of the EDGE series design. The regulator features the innovative SLAM (Shock Limitation and Absorption Mechanism) knob, which is designed to absorb impact energy in the event of a cylinder fall, protecting the vital internal components and the stem-type seat mechanism. The body is constructed from forged brass, reinforced with zinc-aluminum housing caps, ensuring it can withstand the rigors of heavy industrial use. Additionally, the gauges are recessed within the body and shielded by a high-impact ABS gauge guard, significantly reducing the risk of damage during transport or operation.

The ETS4-125-350 is equipped with a CGA 350 inlet connection and a 9/16"-18 UN LH(F) outlet. It utilizes a hybrid internal design with a 0.75" brass piston in the first stage and a 2.7" fabric-reinforced neoprene diaphragm in the second stage to deliver optimal flow control and sensitivity. An external self-reseating relief valve and a sintered nickel-plated bronze inlet filter further enhance the unit's reliability and longevity. Backed by a five-year warranty, this regulator meets or exceeds CGA E-4 and UL 252 standards.
