Description
Leader’s swing Check Valve (Screwed in Cover, PN 20) is supplied in 15 mm to 100 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. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. 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.
