| Installation |
1) Normex Wafer Check valves can be installed between any two standard flanges.
2) The outside diameter of valve is designed considering the minimum P.C.D. available in various flange standards.
3) The valve should be centered between the outside diameter of the pipe flanges simultaneously while tightening the bolts.
4) Recheck that valve outside diameter is equidistant to flange diameter on all sides and fully tighten the bolts. |
