0781-5194 - Victor EST4 Heavy-Duty Acetylene Station Regulator 2-125 PSIG

Advanced Engineering for Pipeline Gas Control

The Victor 0781-5194 EDGE EST4-15-025 Acetylene Station Regulator is a pinnacle of gas control engineering, designed specifically for gas distribution and pipeline systems where reliability and safety are paramount. Unlike cylinder regulators that handle high tank pressures, this station regulator is optimized for a maximum inlet pressure of 200 PSIG, making it the ideal interface between your facility's bulk gas piping and the welder's torch. The unit features a specialized CGA 025 inlet connection tailored for station drops, ensuring compatibility with standard industrial infrastructure.

At the core of the EST4's design is the revolutionary EDGE series architecture. Victor has moved beyond traditional brass bonnets, utilizing a high-strength zinc-aluminum alloy for the housing cap. This material choice provides almost twice the yield strength of brass, offering superior resistance to the rough conditions of industrial environments. The internal mechanism is protected by the SLAM (Shock Limiting and Absorbing Mechanism) knob. This multi-stage crumple zone is engineered to absorb impact energy in the event of a collision or fall, protecting the vital stem and seat assembly from damage that could lead to leaks or failure.

Performance-wise, the regulator boasts a flow coefficient (Cv) of 0.488, delivering uniform flow performance across its 2-125 PSIG delivery range. This high sensitivity allows for precise flame tuning, essential for high-quality oxy-acetylene welding and cutting. The 4-port forged brass body is compact yet robust, measuring 8.2" x 3.8" x 7.1", and meets rigorous industry standards including CGA E-4, UL 252, and ASTM G-175. With its side-entry design and ergonomic layout, the EST4 ensures that gas control is both precise and inherently safe for the operator.
