WCB slow closing check valve inclined disc type

This WCB tilting disc check valve is integrally cast from ASTM A216 carbon steel for high temperature and pressure resistance. Eccentric short-stroke disc with external hydraulic buffer realizes staged slow closing to eliminate water hammer and impact noise. Metal hard seal fits steam and hot oil service. Widely used in power plant, heating, boiler and petrochemical high-pressure high-temperature pipeline systems.

1.Cast WCB carbon steel withstands high temperature up to 425℃, better heat resistance than ductile iron valves, perfectly applied for steam, boiler feed water and thermal circulation pipelines.

2.Short tilting stroke plus hydraulic staged slow closing minimizes water hammer surge, prevents pump reversal and pipeline damage for continuous high-temperature industrial pump stations.

3.Integral cast flange structure with high tensile strength, stable tight sealing under high pressure. Complete size range brings prominent cost advantage for large thermal and petrochemical projects.
