Industrial Pipelines VYC Disc Piston Check Valve 1/4 Brass 304 316 Non-Return Valve for Water Steam Gas

VYC Industrial manufactures a wide range of check valves (non-return valves) in Spain since 1914. The most common models include swing check valves (types 300, 301), lift check valves (types 302, 303), wafer check valves (types 304, 305), and dual-plate check valves (types 306, 307). They are designed for preventing reverse flow in steam, water, gas, and liquid lines. These valves are used in industrial piping where reliable backflow prevention is needed without external actuation.
