0781-5211 - Victor ESL4 Oxygen Station Regulator 125 PSI

Heavy-Duty Oxygen Station Regulator for Industrial Pipelines

The Victor ESL4-125-250F EDGE Series Regulator (0781-5211) represents the pinnacle of gas control technology for station and pipeline applications. Designed specifically for oxygen service in heavy-duty industrial environments, this regulator bridges the gap between your facility's bulk gas distribution system and the operator's torch. Unlike cylinder regulators that handle high inlet pressures (up to 3000 PSIG), the ESL4 is a station regulator engineered to manage inlet pressures up to 350 PSIG, typically found at the drop points of a manifold or pipeline system.

The ESL4 series incorporates Victor's revolutionary EDGE design, which prioritizes safety and durability. The most striking feature is the SLAM (Shock Limitation and Absorption Mechanism) knob. This multi-stage crumple zone is engineered to absorb impact energy in the event of a fall or collision, protecting the vital internal components and the bonnet from damage. This feature significantly extends the service life of the regulator in rough shop environments where equipment is frequently knocked or bumped.

Performance-wise, the ESL4-125-250F delivers a consistent pressure range of 5 to 125 PSIG, making it versatile for cutting, heating, and welding applications. The internal architecture features a straight-through flow path that reduces turbulence and ensures stable flow rates even when line pressure fluctuates. The regulator is equipped with a single, high-contrast delivery gauge that is recessed into the body for protection and color-coded green for immediate gas identification. The inlet connection is a standard "C" size (7/8"-14 threads) female fitting, compatible with most standard station valves, while the outlet is a CGA 022 (9/16"-18 M) fitting for standard oxygen hoses.

Maintenance and safety are further enhanced by the sintered inlet filter, which traps pipe scale and debris before they can damage the regulator seat. The forged brass body provides a robust housing that resists corrosion and wear. Whether you are outfitting a new fabrication facility or upgrading existing station drops, the Victor ESL4-125-250F offers the reliability and precision required for professional operations.
