Description
This dual Plate Wafer Check Valve from Sant covers 50 mm to 400 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 ends make the valve straightforward to remove for servicing without cutting pipe, and are the norm once bore and weight rule out threaded joints. Size and pricing for each option appear in the table above.
