Notes:
1. If supply pressure is variable, assume minimum expected value.
2. Maximum pilot height for up to 500 ft (150 m) of equivalent length of pilot line (pipe plus fittings).
3. Interpolation between data points is permitted.

WET PILOT DESIGN CRITERIA FOR UP TO
(PIPE PLUS FITTINGS)
NOTES:
The dew point of the pilot line air pressure must be maintained
below the lowest ambient temperature to which the dry pilot
actuation system will be exposed. Accumulation of water in the
pilot line connection to the Actuator will lower the air pressure
at which the actuator will open and possibly prevent proper
operation. Also, introduction of moisture into the pilot lines
exposed to freezing temperatures can create an ice buildup
that could prevent proper operation of the Actuator.
An air dryer must be installed where the moisture content
of the air supply is not properly controlled at less than the
required value.
It is recommended that an AMD-3 Nitrogen Maintenance
Device be utilized in dry pilot actuation system applica-
250
tions where the dew point must be maintained below -20°F
(-29°C). Refer to Technical Data Sheet TFP1241.
