Solenoid Operating Specifications
Inlet Pressure Range for Solenoid Operated Valves:
With Internal Pilot Supply: 15 to 150 psig*
(1.03 to 10.3 bar)
With External Pilot Supply: 10" Hg vacuum to 150 psig
(10.3 bar)
Temperature Range (Ambient/Inlet):
Solenoid Operated Valves: -20° to 120°F** (-29° to 50°C)
Low Wattage Solenoids: -20° to 155°F** (-29° to 68°C)
Operator Pilot Pressures:
Maximum Pilot Pressure: 150 psig (10.3 bar)
Minimum Pilot Pressure at 150 psig (10.3 bar) main valve inlet pressures
are given in the following table:
* Minimum Inlet Pressure is dependent on the type of operator
and return used. See Operator Pilot Pressure specifications in
Operating Specifications.
** With the dew point of supply air less than air temperature below
35°F (2°C)

Warning
When a solenoid operator is used as a return for a
manual or mechanical operator, the pilot pressure
applied to the return operator must not exceed 40
psig (2.8 bar). Pilot pressures greater than 40 psig
for a solenoid or air return will cause structural
damage to the manual or mechanical operator and
can also result in injury to the user. If the available
pilot pressure exceeds 40 psig, an external pilot
supply only must be used and a restrictor, part
number 54872-02, must be installed in the pilot
port of the return operator to reduce the return
force to an acceptable level. Pilot pressure to the
restrictor must not exceed 150 psig (10.3 bar).
