Description
Leader dual Plate Check Valve (Flanged, Spring Loaded), available 40 mm to 600 mm at Class 600. 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 connections allow the valve to come out for overhaul with the pipework left in place. The table above gives the catalogue reference and price for each size in the range.
