0781-5224 - Victor EDGE ETS4 Two-Stage Industrial Air Regulator 5-125 PSI

Victor EDGE ETS4-125-590 Industrial Air Regulator Overview

The Victor 0781-5224 EDGE ETS4-125-590 is a premium high-capacity, two-stage industrial air regulator designed to meet the rigorous demands of professional environments. Engineered by Victor, a leader in gas control equipment, this regulator is part of the innovative EDGE series, which blends advanced safety features with a user-friendly, compact design. It is specifically calibrated for Industrial Air service, utilizing a CGA 346 inlet connection and providing a delivery pressure range of 5 to 125 PSIG. The two-stage mechanism is the defining feature of the ETS4 series, ensuring that the outlet pressure remains constant and precise throughout the life of the cylinder, regardless of the decreasing inlet pressure. This makes it an excellent choice for applications requiring steady flow and exacting pressure control, such as pneumatic testing, laboratory work, and specialized industrial processes.

Durability is at the core of the EDGE design. The regulator features a forged brass body and a die-forged brass spring housing cap, offering exceptional strength. To further protect the device, Victor has integrated a high-impact ABS gauge guard that recesses the 1.5-inch gauges into the body, shielding them from accidental damage. The SLAM (Shock Limitation and Absorption Mechanism) knob is another critical safety innovation; designed with a multi-stage crumple zone, it absorbs impact energy in the event of a cylinder fall, protecting the regulator's internal stem and seat mechanism. This attention to structural integrity ensures a long service life even in tough shop environments.

Performance-wise, the ETS4-125-590 boasts a flow coefficient (Cv) of 0.488, allowing for uniform flow performance across a wide range of cylinder pressures. The internal components include a stainless steel diaphragm for accurate, long-lasting service and a stem-type seat mechanism that aids in sealing. For added safety, the unit includes an external self-reseating relief valve and a sintered nickel-plated bronze inlet filter to trap particulates. The side-mounted pressure adjustment knob promotes a natural hand position, making adjustments easy and safe. Backed by a 5-year warranty and meeting CGA E-4, UL 252, and ASTM G-175 standards, this regulator represents the pinnacle of gas control technology.
