Description
Leader’s dual Plate Check Valve (Flanged, Spring Loaded) is supplied in 50 mm to 600 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. A cast carbon steel body to ASTM A216 WCB handles the temperatures and pressures of steam and hot oil, where bronze or iron would not be rated. Flanged ends make the valve straightforward to remove for servicing without cutting pipe, and are the norm once bore and weight rule out threaded joints. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
