PPrecautionary Note: Not recommended for use with
reciprocating pumps and similar applications, which may induce
repetitious vibrations. Low ow rates which do not fully open the
valve may result in undesirable noise and premature valve failure.
Upstream ow disturbances, which create turbulence, may also
result in rapid wear. Therefore, it is recommended that a minimum
of 10 diameters of straight pipe be provided between the check
valve and any upstream ow disturbances such as pumps, control
valves, elbows, etc. See Installation Manual for details.
