Description
This dual Plate Check Valve (Wafer Type, Spring Loaded) from Leader covers 50 mm to 600 mm at Class 150. 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. WCB carbon steel construction, rated for the steam and thermal-oil duties that rule out lighter body materials. A wafer body adds almost nothing to the length of the pipe run. Normally fitted on pump discharges and at the point a branch joins a common header. Size-by-size catalogue numbers and pricing appear in the table above.
