Description
Leader’s swing Check Valve (Bolted Cover) is supplied in 50 mm to 300 mm at Class 900. 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. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
