Description
Sant’s single Plate Wafer Check Valve is supplied in 50 mm to 400 mm at PN 16. 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. A wafer body adds almost nothing to the length of the pipe run. Full dimensions and current pricing for every size are listed in the table above.
