API 600  Swing Check valve offers durability throughout a wide range of industrial applications, boiler plant and rugged environments.

The seat Ring and Wedge Disc are ground and lapped to a mirror finish that provides matching sealing surfaces. A free rotating Disc design to minimize localised wear on sealing surfaces. Standard internal HINGE design eliminates body penetration and allows ease of maintenance, since all parts are accessible from the top and the valve can be serviced insitu. High strength alloy steel STUD BOLTS and series HEX NUTS used.
