Description
Leader horizontal Lift Check Valve (Screwed in Cover, PN 16), available 8 mm to 150 mm at PN 16. 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. Screwed BSP ends keep installation simple at small bores and allow a valve to be changed with two wrenches. 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.
