0781-5193 - Victor EDGE EST4 Oxygen Station Regulator, 5-125 PSIG, CGA-024

Victor EDGE EST4-125-024 Oxygen Station Regulator Overview

The Victor EDGE EST4-125-024 is a premium heavy-duty station regulator designed specifically for oxygen distribution and pipeline systems. Engineered to meet the rigorous demands of industrial environments, this regulator serves as the critical control point between a facility's low-pressure pipeline drop and the welding or cutting equipment. Unlike cylinder regulators designed for high-pressure inputs, the EST4 is optimized for a maximum inlet pressure of 200 PSIG, utilizing a CGA-024 inlet connection that ensures compatibility with standard oxygen station fittings.

At the core of the EST4's design is a robust 4-port forged brass body paired with a zinc-aluminum housing cap. This alloy cap provides nearly twice the yield strength of traditional brass caps, significantly enhancing the unit's resistance to deformation and thread damage over time. The internal mechanism features a stem-type seat and a 0.488 Cv flow coefficient, delivering uniform flow performance across a variety of line pressures. This ensures high sensitivity and accuracy in delivery pressure, which is adjustable from 5 to 125 PSIG, making it suitable for a wide range of cutting, heating, and welding applications.

Safety and compliance are paramount in the design of the EDGE series. The EST4-125-024 meets or exceeds CGA E-4, UL 252, and ASTM G-175 industry standards. It incorporates an external self-reseating relief valve and a sintered bronze inlet filter to protect the internal components from particulate contamination. The regulator is also equipped with a 2.5-inch delivery gauge featuring updated artwork and high-contrast graphics, allowing operators to monitor pressure settings quickly and accurately from a distance.

The unit's physical architecture is designed to be both compact and ergonomic. The side-entry inlet and rear-entry options (depending on specific configuration) facilitate clean installation on pipeline drops, minimizing protrusion into the workspace. With its advanced materials and precision engineering, the Victor EST4-125-024 represents the standard for reliability in gas distribution technology.
