998186 - V-54 4-Way Manifold with CV-2 Check Valves

Technical Overview of the V-54/CV-2 Combo

The ESAB V-54/CV-2 Combo (SKU: 998186) is a specialized gas distribution assembly designed for industrial piping and welding gas management. This unit integrates the functionality of the industry-standard V-54 four-way manifold block with the safety features of CV-2 check valves. Constructed from high-grade brass, the manifold offers superior resistance to corrosion and mechanical stress, making it suitable for a wide range of industrial environments, including workshops, laboratories, and manufacturing floors.

The core component, the V-54 manifold, features a cross-style configuration with multiple ports, typically tapped for 1/4-inch NPT connections. This allows for the efficient splitting of a single gas supply line into multiple outlets, facilitating the operation of multiple torches or tools from a single regulator or cylinder bank. The inclusion of CV-2 check valves is a critical technical enhancement; these unidirectional valves are engineered to permit gas flow in only one direction, effectively preventing backflow. Backflow in gas systems can lead to cross-contamination of gases or, in oxy-fuel applications, dangerous flashbacks. By integrating these valves directly into the manifold assembly, the V-54/CV-2 Combo ensures a compact, leak-resistant solution that adheres to best practices in gas piping safety.

Installation of this combo unit is straightforward due to the standardized NPT threading, which is compatible with a vast array of commercial fittings, hoses, and regulators. The brass body is machined to tight tolerances to ensure secure sealing with thread sealants or tape. Whether used for inert shielding gases like Argon and CO2, or for fuel gases and oxygen (subject to cleaning and compatibility checks), this assembly provides a robust node in any gas distribution network.
