Normex,
pioneers and manufacturers of unique Ball Check Valves, Ball Foot Valves, Hydrodynamic Guided NRVS have introduced yet another design of Non-return valve Wafer
check Valves. Normex wafer check
valves are simple in construction have sturdy design & are reliable in operations. These valves are very useful where weight of the valve is required be low
& there is a space constraint for valve fitment. The face to face distance in these valves is extremely less as compared to standard valves.

Flanges
|
Between any standard flanges
|
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.
