Description
Leader’s swing Check Valve (Forged Brass, Screwed in Cover, PN 20) is supplied in 15 mm to 50 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. Forged brass keeps cost and weight down at small bores, where a cast body’s strength is not required. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
