Description
Leader’s reflux Valve (Bolted Cover) is supplied in 50 mm to 300 mm at PN 20. 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. Used on pump delivery lines and wherever two sources feed a shared main. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
