Description
Leader horizontal Lift Check Valve (Bolted Cover), available 15 mm to 50 mm at Class 300. 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 A105 gives a dense, void-free body — why forged construction is specified for small-bore high-pressure duty. Flanged connections allow the valve to come out for overhaul with the pipework left in place. 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.
