0781-3563 - Victor VTS252C-350 Methane/Hydrogen Regulator CGA 350

Precision Control for Methane and Hydrogen Applications

The Victor 0781-3563 VTS252C-350 Regulator is a premium two-stage gas control device engineered specifically for Methane and Hydrogen service. Part of the renowned VTS 250 Series, this medium-duty regulator is designed to provide exceptional performance in applications requiring a constant delivery pressure over a wide range of decreasing inlet pressures. As gas cylinders deplete, single-stage regulators often allow delivery pressure to rise, but the two-stage mechanism in the VTS252C-350 compensates for these fluctuations, ensuring a steady flow and consistent pressure from full cylinder to empty.

Constructed with a die-forged brass body and a heavy-duty spring housing cap, this regulator is built to withstand the rigors of industrial and laboratory environments. The internal components are equally robust, featuring a fabric-reinforced neoprene diaphragm that offers precise response to pressure changes and long-lasting service life. The regulator is equipped with a CGA 350 inlet connection, making it compatible with standard Methane and Hydrogen cylinders, and features a 9/16"-18 LH(M) outlet connection for secure attachment to hoses and downstream equipment.

Operational precision is further enhanced by the inclusion of a stainless steel ball in the adjustment key, which reduces friction and allows for smooth, easy pressure settings. A Delrin insert bushing adds to the durability and ease of adjustment. Safety is paramount in gas regulation, and the VTS252C-350 includes an external self-reseating relief valve (note: not designed to protect downstream equipment) and a sintered bronze inlet filter to trap particulates before they can damage the seat mechanism. With a delivery range of 4-80 PSIG and a maximum inlet pressure of 3000 PSIG, this regulator is an ideal choice for professionals demanding accuracy and reliability.
