Notes:
a. To minimize noise, ensure the flow rate in the piping is
less than three meters (10ft)/second and the differential
pressure is less than 35 psi (241 kpa). Operating within the
cavitation zone or an operating differential pressure above
35 psi (241 kpa) may result in noise.
b. Maximum recommended differential pressure in
open position. Do not exceed recommended differential
pressure (pressure drop) or integrity of parts may be
affected. Exceeding maximum recommended differential
pressure voids product warranty.
c. kvs = m3/h (P = 100 kPa) Cv = kvs x 1.156
d. Requires properly conditioned waterper EN-205 Water
System Guideline, F-26080. Actuator close off force
recommendations must be observed to meet ANSI Class V.
