Description
This reflux Valve, Cast Iron Disc with Rubber Ring, IS 5312 from Leader covers 50 mm to 300 mm at PN 16. Fitted to prevent flow reversing when a pump stops or a line depressurises. Orientation matters: a swing pattern needs the correct attitude to seat properly, so confirm the intended mounting before ordering. Grey cast iron to IS 210 keeps the cost sensible in the larger sizes, provided the duty is steady rather than shock-loaded. Flanged connections allow the valve to come out for overhaul with the pipework left in place. Size-by-size catalogue numbers and pricing appear in the table above.
