Cautions
When ordering valve body only: Use the fi rst six
positions to confi gure the valve.
When ordering actuator only: Use the last seven
positions to confi gure the actuator. Prefi x with
the letter A.
Inverted fl are fi ttings must be ordered separately.
See actuator accessories, bulletin F-26496,
for fi tting part numbers.
End switch is not available for 277 Vac models if
actuator temperature rating is high temperature.
Actuators with Terminal blocks require end switch
and the end switch is 24 Vac at 101 mA min. to
5A max.
End switch is 24 - 240 Vac at 101 mA min to 5A
max. and 9 to 30- Vdc at 100 mA max. for actuators
rated 240 V or less. End switch is 277 Vac at 101 mA
min. to 5A max. for actuators rated 277V.

T = General 3 = General temperature
S = Steam 4 = High temperature
If body confi guration is T, actuator temp rating can be 3 or 4. If actuator temp rating is 3, body style must be T.
If body confi guration is S, actuator temp rating must be 4. If actuator temp rating is 4, body style can be S or T.
