Check Valves
For use in Grooved-End Piping Systems
FLOW DATA:
The approximate friction
losses, based on the Hazen and
Williams formula, expressed
in equivalent length of pipe is
given below. The friction losses
have been calculated on the
basis of fow rates typically
used with each size valve.
IMPORTANT NOTE:
Check valve life may be shortened and system damage may occur if check valves are installed too close to a source of unstable fow.
Check valves must be installed at a reasonable distance away from pumps, elbows, expanders, reducers or other similar devices.
Sound piping practices dictate a minimum of fve (5) times the pipe diameter for general use. Distances between three (3) and fve
(5) diameters are allowable provided the fow velocity is less than 8 feet per second. Distances less than 3 diameters are not recommended.
This valve may be installed vertically or horizontally. In a horizontal installation, the hinge pin is to be located on top.
Not for use in copper systems.
