CJ/T 282 Check Valve

A CJ/T 282 check valve is an advanced, non-return water valve designed and manufactured in strict compliance with the Chinese urban construction industry standard CJ/T 282, which governs high-integrity, silent check valves for municipal water supply and drainage networks. Engineered with a streamlined internal fluid passage and a spring-loaded, quick-closing disc (often faced with EPDM or NBR), the valve closes rapidly prior to the physical reversal of water flow. This predictive shut-off completely eliminates destructive water hammer shockwaves, protecting pumps, municipal piping, and pipeline fittings from high-pressure surge damage. Civil engineering contractors and water utility managers can protect valuable pump stations and eliminate water hammer shock by importing certified CJ/T 282 check valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
