The Victor® SR460A-510 (0781-0584) is a heavy-duty, acetylene regulator designed for high-performance cutting, welding, and heating applications. Ideal for use with larger cylinders, it provides consistent delivery pressure and superior control, even as cylinder pressure decreases — making it perfect for demanding industrial operations.

Built with a forged brass body and housing cap, the SR460A-510 combines rugged durability with precision regulation. The 3.25″ stainless steel diaphragm and 2.5″ brass gauges offer clear pressure readings, and the regulator is engineered to deliver or exceed its stated upper pressure range.
