When your welding shop or fabrication facility requires dependable compressed air regulation, the Victor SR 450D-346 Heavy Duty Regulator stands out as a top-tier choice. Part of the legendary SR 450 series, this regulator is designed for professionals who demand durability and precision. Whether you are running pneumatic tools, supplying air for plasma cutting operations, or managing test benches, this single-stage regulator delivers consistent performance you can trust. Its heavy-duty construction minimizes downtime and maintenance, keeping your operations running smoothly.
Built to last, the SR 450D-346 features a solid die-forged brass body and housing cap, which are far more durable than standard bar stock or cast components. The internal mechanism is equally impressive, boasting a stem-type seat mechanism and a precision-machined nozzle for maximum flow control. The 3.25-inch stainless steel diaphragm is a standout feature, offering superior sensitivity to pressure changes and ensuring that your delivery pressure remains stable even as the cylinder pressure decreases. This model is calibrated for a delivery range of 5-125 PSIG, covering the vast majority of shop air requirements.
User convenience and safety are built into every aspect of the design. The large 2.5-inch brass gauges are easy to read from a distance, allowing operators to monitor tank levels and line pressure at a glance. The adjusting screw features a comfortable T-handle design that makes setting your desired pressure quick and effortless. The inclusion of a sintered inlet filter prevents debris from entering the regulator, a common cause of regulator failure in dirty shop environments. With a flow coefficient (Cv) of 0.27, this regulator provides ample flow for medium to high-capacity applications. Invest in the Victor 0781-0532 for a regulator that combines the ruggedness required for heavy industry with the precision needed for delicate work.
