SWING CHECK VALVES

DESIGN FEATURES

Body and Cover

The body is cast with uniform sections and generous radius fillets to prevent stress on all sides. The body is spherical in shape to prevent minimum turbulence, erosion and resistance to flow. The body-cover joint is male-female in ASME class 150-600 and ring type joint in class 900 and over. The cover material is identical to the body. The check valves are designed to give resistance against water hammer caused by a sudden reverse flow. Gasket materials can be supplied according to customer’s requirement.

Disc

The disc is constructed to have one piece to endure severe service conditions. It has a sufficient seating surface area which is ground and lapped to a mirror finish. The disc is of one-piece construction and is heat treated to deliver the required mechanical properties and hardness. It is securely fastened to the hinge by means of a lock nut with a cotter pin.

Seat Ring

The seat rings are designed to prevent any turbulence and damage by corrosion. They are forged or rolled in one piece and then seal welded and overlaid, if required. The forget seat ring is heat-treated to deliver the best mechanical properties and required hardness.

Arm

The disc stability is maintained while the disc is lifted by a hydrodynamic force at a flow including pulsating. The arm is designed to minimize water hammer because the disc goes to seat immediately upon cessation of flow due to heavy balanced weight.

Hinge

The hinge is designed to eliminate body penetration and allow ease of maintenance because all parts are accessible from the top. Body penetration is sealed with blind flange and spiral wound gasket. The hinge pin is located near the disc center of gravity resulting in minimizing sealing surface radius rotation and velocity.

End Connections

The standard flange ends have a raised face serrated finish type which conforms to ASME B16.5 RF. ASME class 600 valves are supplied with RTJ end flanges on request.
