Description
Leader’s horizontal Lift Check Valve (Screwed in Cover, PN 25, Flanged) is supplied in 15 mm to 100 mm at PN 25. Check valves stop reverse flow without any external operation — line pressure alone opens and closes them. On a pump discharge they prevent backspin and the water hammer that follows an abrupt stop. 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. Normally fitted on pump discharges and at the point a branch joins a common header. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
