a - To minimize noise, ensure the flow rate in the piping is less than 10 ft (3m) / second and the
differential pressure is less than 35 psi (241 kPa). Operating with differential pressures above 35
psi may result in additional noise but is acceptable up to 87 psi (600 kPa). Operating within the
cavitation zone may result in noise and internal valve damage.
b - Maximum recommended differential pressure in open position. Do not exceed recommended
differential pressure (pressure drop), as integrity of parts may be affected.
c - Refer to Seat Leakage Classes table.
