0781-3573 - Victor VTS253B-320 Two-Stage CO2 Regulator (2-40 PSIG)

Victor VTS253B-320 Medium Duty Two-Stage CO2 Regulator

The Victor VTS253B-320 (SKU: 0781-3573) is a precision-engineered two-stage regulator designed specifically for Carbon Dioxide (CO2) applications requiring stable delivery pressures. Part of the VTS 250 Series, this medium-duty regulator excels in environments where maintaining a constant outlet pressure is critical, regardless of fluctuations in the inlet pressure from the gas cylinder. With a delivery range of 2-40 PSIG, it is particularly well-suited for applications demanding accurate low-to-medium pressure control.

Constructed for longevity and reliability, the regulator features a die-forged brass body and a heavy-duty spring housing cap. This robust construction ensures the unit can withstand the rigors of industrial use while maintaining high performance. The internal mechanism includes a fabric-reinforced neoprene diaphragm (1.3" and 1.75") which provides exceptional sensitivity and long-lasting service life. A stainless steel ball located in the adjustment key allows for smooth, low-friction pressure settings, while the Delrin insert bushing enhances durability and ease of adjustment.

Safety and maintenance are key components of the VTS253B-320 design. It includes an external self-reseating relief valve (though not designed to protect downstream equipment, it adds a layer of safety at the regulator level). The inlet is protected by a sintered filter made from electroless nickel-plated bronze, which effectively traps particulates and prevents damage to the seat mechanism. The stem-type seat mechanism aids in positive sealing, ensuring leak-free operation. The unit comes equipped with 2-inch steel gauges displaying inlet pressure (up to 4000 PSIG) and outlet pressure (up to 60 PSIG), providing clear visual indicators for the operator.

This regulator connects via a CGA 320 inlet, the standard for CO2 cylinders, and utilizes a CGA 032 5/8"-18 UNF outlet connection. With a flow coefficient (Cv) of 0.082, it delivers consistent performance for medium-capacity applications. Whether used for laboratory testing, beverage systems, or industrial shielding gas delivery, the VTS253B-320 offers the reliability expected from Victor's professional-grade equipment.
