0781-5199 - Victor EDGE ELC4 Oxygen Regulator for Liquid Cylinders, 125 PSI

Victor EDGE ELC4-125-540R Oxygen Regulator for Liquid Cylinders

The Victor EDGE ELC4-125-540R is a premium gas regulator specifically engineered to manage the vaporized gas flow from liquid oxygen vessels. Unlike standard high-pressure regulators designed for compressed gas cylinders, the ELC4 Series is optimized for the unique pressure and flow characteristics of liquid cylinders (dewars). With a delivery pressure range up to 125 PSIG and a standard CGA 540 inlet, this regulator ensures consistent performance for industrial applications requiring reliable oxygen supply.

Safety and durability are at the core of the EDGE series design. This model features Victor's patented SLAM (Shock Limiting and Absorbing Mechanism) knob, which protects the regulator internals and the adjusting screw from damage in the event of a cylinder fall or impact. The housing cap is constructed from high-strength Zinc-Aluminum alloy, providing nearly twice the yield strength of traditional forged brass caps. The body itself is a robust 4-port forged brass design, ensuring longevity even in harsh industrial environments.

The regulator is equipped with a single, large 2.5-inch delivery gauge featuring high-contrast graphics for easy reading from a distance. Because liquid cylinders typically operate at lower inlet pressures than high-pressure cylinders, the internal architecture of the ELC4 is tuned to provide stable flow without the freeze-up issues sometimes associated with high-draw applications. It meets or exceeds all relevant safety standards, including CGA E-4 and UL 252, making it a trusted choice for professional gas distribution systems.
