Instalation Tips
Always follow standard safety procedures when working on a valve.
Check valves must be installed such that the arrow on the body of the valve points in the direction of desired fluid flow.
All check valves should be installed at least ten pipe diameters away from upstream pumps, elbows, fittings or equipment.
Check valves without springs should be installed with the bonnet up, and the angle of incline should be no more the 45° from horizontal. Also, the roll angle of the valve bonnet should be no more than 45° from side to side
