0781-5186 - Victor EDGE ESS7 High Flow Methane Hydrogen Regulator CGA 350

Heavy-Duty Victor 0781-5186 Regulator for High Flow Applications

Welders and fabricators requiring reliable high-flow gas delivery for Methane or Hydrogen applications can trust the Victor 0781-5186 EDGE ESS7-200-350 Regulator. This unit is the modern successor to the legendary SR 700 series, bringing updated engineering and ergonomic advancements to the shop floor. Built to handle a maximum inlet pressure of 3000 PSIG, this regulator delivers a consistent output between 10 and 200 PSIG, making it ideal for heavy-duty cutting, heating, and other high-consumption processes where flow stability is non-negotiable.

The ESS7-200-350 is defined by its compact yet rugged industrial design. It features a CGA 350 inlet connection and a standard 7/8"-14 RH(M) outlet, ensuring compatibility with standard high-pressure cylinders and hoses. The regulator boasts a flow coefficient (Cv) of 0.488, which translates to superior flow performance across a wide range of cylinder pressures. The heart of the regulator is its large 2.7-inch diaphragm, made from fabric-reinforced neoprene. This large surface area allows the regulator to react quickly to changes in demand, maintaining a steady flame or flow even during rapid consumption spikes.

Victor has revolutionized regulator design with the EDGE series by prioritizing the physical protection of the device. The gauges are recessed within the body profile, significantly reducing the chance of breakage if the unit is bumped or dropped. The SLAM knob adds another layer of defense, absorbing impact energy to prevent damage to the adjusting screw and internals. Additionally, the sintered inlet filter—the same trusted component used in all Victor industrial regulators—prevents particulate contamination from entering the seat assembly, prolonging the service life of the unit. For professionals who demand precision, durability, and safety, the Victor EDGE ESS7 is the definitive choice.
