Description
Leader dual Plate Check Valve (Solid Lug Type, Spring Loaded), available 50 mm to 300 mm at Class 150. 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. Lugged bodies bolt to each flange independently, so downstream pipework can be removed with the valve still holding the line. The table above gives the catalogue reference and price for each size in the range.
