0781-2401 - Victor SR 360A-510 High Capacity Acetylene Regulator

Precision Control for Industrial Acetylene Applications

The Victor SR 360A-510 (SKU: 0781-2401) is a premium single-stage regulator designed for heavy and medium-duty industrial applications requiring high-capacity acetylene flow. Part of the renowned SR 360 / SR 350 series, this regulator is engineered to provide reliable performance in environments where durability and precision are paramount. It features a robust die-forged brass body that withstands the rigors of daily industrial use, ensuring a long service life even in harsh shop conditions.

Technically, the SR 360A-510 excels with its large 2.75-inch fabric-reinforced neoprene diaphragm. This substantial diaphragm area allows for exceptional sensitivity and responsiveness to pressure changes, maintaining a stable delivery pressure of 2-15 PSIG even as the cylinder pressure decays. While single-stage regulators typically exhibit a slight rise in delivery pressure as the inlet pressure drops, the high-capacity design of the SR 360 minimizes this effect, making it suitable for most cutting, heating, and welding applications where absolute constant pressure (provided by two-stage models) is not critical.

The unit is equipped with large 2.5-inch brass gauges that provide clear visibility of both cylinder and delivery pressures. Safety and longevity are addressed through a sintered bronze inlet filter, which prevents particulate matter from damaging the internal seating mechanism, and an external self-reseating relief valve. The internal mechanism utilizes a stem-type seat and a stainless steel ball and key, further enhancing the regulator's reliability. With a maximum inlet pressure rating of 3000 PSIG and a standard CGA 510 connection, this regulator is a versatile workhorse for professional gas control systems.
