0781-5218 - Victor EDGE ETS4 Two-Stage Oxygen Regulator CGA-540

Victor EDGE ETS4-125-540 High Capacity Two-Stage Oxygen Regulator

The Victor EDGE ETS4-125-540 is a premium two-stage oxygen regulator designed for professionals who demand precision, safety, and durability in industrial environments. As part of the revolutionary EDGE series, this regulator represents a significant leap forward in gas control technology, blending advanced engineering with user-centric design. The two-stage mechanism is the core of its performance, ensuring that delivery pressure remains constant throughout the life of the cylinder. Unlike single-stage regulators that may require frequent adjustment as the tank pressure drops, the ETS4 maintains a steady 5-125 PSIG output, making it ideal for critical applications where flame consistency is paramount.

Safety and durability are built into every aspect of the ETS4. The regulator features a forged brass body and a high-strength zinc-aluminum housing cap, providing a robust foundation that withstands the rigors of daily use. One of the standout features is the SLAM (Shock Limitation and Absorption Mechanism) knob. This color-coded, impact-absorbing knob is designed to protect the regulator's internal components and the adjusting screw in the event of a fall or collision. Furthermore, the gauges are recessed into the body, shielding them from damage—a common failure point in traditional regulator designs. This thoughtful architecture ensures the unit remains operational and accurate even in tough shop environments.

Operational efficiency is enhanced by the regulator's ergonomic layout. The side-mounted adjustment knob allows for a more natural hand and body position during setup, reducing strain and improving safety by keeping the operator clear of the cylinder valve path. Internally, the regulator utilizes a stem-type seat mechanism and a stainless steel diaphragm, ensuring accurate, long-lasting service. A nickel-plated bronze sintered inlet filter prevents debris from entering the system, further extending the lifespan of the unit. With a flow coefficient of 0.488 Cv, the ETS4 delivers uniform flow performance across a wide range of cylinder pressures. Backed by a five-year warranty and meeting stringent CGA E-4 and UL 252 standards, this regulator is the definitive choice for heavy-duty fabrication, structural steel work, and maintenance applications.
