Description
Covering 50 mm to 350 mm at Class 900, this is Leader’s swing Check Valve (Pressure Seal Cover). Fitted to prevent flow reversing when a pump stops or a line depressurises. Orientation matters: a swing pattern needs the correct attitude to seat properly, so confirm the intended mounting before ordering. WCB carbon steel construction, rated for the steam and thermal-oil duties that rule out lighter body materials. Butt-welded ends give a permanent joint with no potential leak path, used where the line is not intended to be broken. Every size in the range is listed above with its catalogue number and price.
