Description
Leader horizontal Lift Check Valve (Union Cover, SS Trim, PN 25), available 15 mm to 80 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. 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. The table above gives the catalogue reference and price for each size in the range.
