0781-0584 - Victor SR460A-510 Heavy Duty Acetylene Regulator, CGA-510, 2-15 PSIG

Victor SR460A-510 Heavy Duty Acetylene Regulator Overview

The Victor SR460A-510 (SKU: 0781-0584) is a premium single-stage acetylene regulator designed for heavy-duty and high-capacity industrial applications. Part of the renowned SR 450 Series, this regulator is engineered to provide reliable performance in demanding environments such as structural steel fabrication, repair and maintenance, and general industrial manufacturing. The unit is constructed with a die-forged brass body and housing cap, ensuring exceptional strength and resistance to workplace wear and tear. This robust construction allows the regulator to withstand a maximum inlet pressure of 3000 PSIG while maintaining structural integrity.

At the core of the SR460A-510 is a large 3.25-inch stainless steel diaphragm. This substantial diaphragm size is critical for maintaining accurate delivery pressure, offering a delivery range of 2 to 15 PSIG. The stainless steel material provides long-lasting service life and precise response to pressure changes. The regulator utilizes a stem-type seat mechanism, which uses the inlet pressure to assist in sealing, thereby enhancing the reliability of the closure. To ensure the longevity of the internal components, the unit features a sintered bronze inlet filter that is electroless nickel-plated; this filter effectively traps particulates and prevents debris from damaging the seat mechanism.

Operational ease and safety are paramount in the design of the SR460A-510. The regulator is equipped with a brass adjusting screw featuring a forged T-handle, allowing operators to make easy and precise pressure adjustments even while wearing protective gloves. A Delrin insert bushing is incorporated into the cap to ensure smooth operation of the adjusting screw and to reduce friction and wear. For safety, the regulator includes an external self-reseating relief valve (on high-pressure models, though standard on this series design) to protect the housing from over-pressurization. The 2.5-inch brass gauges provide clear visibility of both cylinder and delivery pressures, ensuring operators can monitor gas supply at a glance. This regulator connects via a standard CGA-510 inlet and provides a 9/16"-18 LH(M) outlet connection.
