CAST STEEL SWING CHECK VALVES
CAST STEEL SWING CHECK VALVES
KVC (UK) LTD Swing Check valves are manufactured to BS 1868, B16.34, and tested to API Std.598
Swing Check valves are automatically actuated. They are used to prevent fl ow reversal in piping systems. They are suitable for service in the horizontal and the vertical orientation (fl ow up through valve). Swing check valves have low pressure drop characteristics and are best suited for moderate velocity applications. There is no tendency for the seating surfaces of swing check valves to gall or score, this is due to the fact that the disc meets the fl at seat squarely and there is no rubbing upon contact.
BODY AND BONNET
Spherical body with large radius, allows stress and turbulence to be minimized
Strong construction assures safety, even above pressure and temperature limits.
BODY-BONNET JOINT / GASKET
Range of materials to suit Pressure Classes
DISC
Designed to close on its own weight to stop backfl ow.
WELDED-INSEAT RING
Seat ring is seal welded to eliminate potential leak paths.
