1.6 MPa Check Valve

A 1.6 MPa check valve is an automatic, self-operating non-return valve designed to prevent fluid backflow in piping networks operating at nominal working pressures up to 1.6 MPa (PN16 / 232 PSI). Available in swing, lift, or dual-plate wafer configurations, it utilizes the forward velocity of the process fluid to lift the disc open and automatically seals shut via backpressure or spring assistance when flow stops. Conforming to standards like EN 12334, GB/T 12235, and API 594, these reliable non-return valves are primary specifications in municipal water pumping stations, commercial building HVAC hydronic loops, and industrial wastewater lines, allowing civil engineers and utility contractors to protect upstream pumps from backflow damage by importing certified 1.6 MPa check valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
