0781-3513 - Victor VTS250D-580 Two-Stage Inert Gas Regulator CGA 580

Precision Two-Stage Inert Gas Regulation

The Victor 0781-3513 VTS250D-580 is a high-performance two-stage regulator designed specifically for medium-duty inert gas applications. Part of the renowned VTS 250 Series, this unit is engineered to provide a constant delivery pressure over a wide range of decreasing inlet pressures. This characteristic makes it an essential component for laboratory testing, precise welding applications, and industrial processes where pressure stability is critical to the outcome of the work.

Constructed with a die-forged brass body and a brass spring housing cap, the VTS250D-580 offers exceptional strength and durability suitable for industrial environments. The internal mechanism features a stem-type seat that aids in positive sealing, while the stainless steel diaphragm provides accurate, long-lasting service life. A key technical feature is the 0.082 Cv flow coefficient, optimized for medium-capacity flow requirements. The regulator is equipped with an electroless nickel-plated bronze sintered inlet filter to protect the internal components from particulate contamination.

Ease of operation is ensured by the Delrin insert bushing and a stainless ball in the adjustment key, allowing for smooth, low-friction pressure settings. The unit includes two 2-inch steel gauges: a 4000 PSIG inlet gauge and a 200 PSIG outlet gauge, providing clear visual monitoring of system status. With a delivery range of 5 to 125 PSIG and a maximum inlet pressure of 3000 PSIG, this regulator is versatile enough for a variety of inert gases utilizing the CGA 580 connection standard.
