998317 - Victor CV-4 Torch Check Valve Combo Kit

Victor V-54/CV-4 Combo: Engineered for Gas Safety

The Victor V-54/CV-4 Combo (SKU: 998317) is a specialized safety kit designed to enhance the operational security of oxy-fuel welding and cutting apparatus. At the core of this package are the Victor CV-4 Check Valves, which are precision-engineered devices intended to prevent the reverse flow of gases. Reverse flow is a critical hazard in oxy-fuel systems, occurring when a pressure imbalance forces gas from one line back into the other, potentially creating a mixed-gas explosive atmosphere within the hose or regulator. The CV-4 valves effectively mitigate this risk by utilizing a spring-loaded mechanism that closes instantly upon detection of back-pressure.

These check valves are designed for Torch Mounting, placing the safety device as close to the point of use as possible. They feature standard B-Size (9/16"-18) threads, ensuring compatibility with the vast majority of industrial torch handles and cutting attachments. The kit typically includes a pair of valves: one with right-hand threads for oxygen and one with left-hand threads for fuel gas, preventing cross-connection during installation. Constructed from high-quality brass, the CV-4 valves offer robust durability and corrosion resistance, suitable for use with Acetylene, Propane, Propylene, and Natural Gas.

Professionals rely on Victor's V-Series and CV components for their consistent flow characteristics and low cracking pressure, which minimizes flow restriction while maintaining a reliable seal against reverse flow. This combo kit is an essential component for any safety-conscious fabrication environment, meeting or exceeding industry standards for gas equipment accessories.
