0781-3510 - Victor VTS 250 Series Two-Stage Air Regulator CGA 346

Precision Control for Industrial Air Applications

The Victor VTS250C-346 Air Medium Duty Two Stage Regulator (0781-3510) is engineered for professionals who demand unwavering accuracy and durability in their gas control equipment. Designed specifically for compressed air applications, this regulator is part of the renowned VTS 250 Series, known for its ability to maintain a constant delivery pressure over a wide range of decreasing inlet pressures. This feature is critical for testing, calibration, and precision pneumatic applications where pressure fluctuation could compromise results or equipment performance.

Robust Construction and Design

Built to withstand the rigors of industrial environments, the VTS250C-346 features a die-forged brass body and a heavy-duty spring housing cap. This construction provides exceptional strength and resistance to external damage. The internal components are equally robust, featuring a stainless steel diaphragm that offers accurate, long-lasting service life compared to standard rubber diaphragms. The regulator utilizes a stem-type seat mechanism which aids in positive sealing, reducing the risk of leaks and ensuring safety during operation.

Advanced Performance Features

This two-stage regulator excels in delivering precise pressure control. It takes high-pressure input (up to 3000 PSIG) and steps it down in two stages to a stable working pressure between 4 and 80 PSIG. The inclusion of a Delrin insert bushing and a stainless ball in the key mechanism ensures that adjustments are smooth and effortless, allowing operators to dial in the exact pressure required with ease. Additionally, the unit is equipped with an electroless nickel-plated bronze sintered inlet filter, which protects the internal valve components from particulate contamination, further extending the lifespan of the regulator.

Safety and Specifications

Safety is paramount in the design of the VTS 250 Series. It includes an external self-reseating relief valve (note: not designed to protect downstream equipment) and 2-inch steel gauges that provide clear readings of both inlet and outlet pressures. The inlet connection is a standard CGA 346 for air, and the unit is rated for a maximum inlet pressure of 3000 PSIG. Whether for laboratory use, manufacturing processes, or general industrial air supply, the Victor VTS250C-346 stands as a reliable choice for consistent performance.
