Section 4: Service Condition Limitations (Limitation of Use)

(Limitation of Use)
Maximum Operating Pressure:
– Pneumatic Service
– Up to 120 psig (8.3 barg)
Ambient Temperature:
Temperature extremes require different solutions to maintain actuator operational
integrity and reliability. For each El-O-Matic F-Series actuator is available in three
different temperature executions.
– -20°C to +80°C (-4°F to +176°F) Standard temperature
– -10°C to +120°C (+14°F to +250°F) High Temperature
– -40°C to +80°C (-40°F to +176°F) Low Temperature
Torque Output Range:
– Double-Acting El-O-Matic F-Series actuators, requiring pressure to rotate
in either direction, are available with a torque range between 4.8 Nm
(44 lbf.in) and 6,490 Nm (59000 lbf.in)
– The El-O-Matic F-Series spring-return models require pressure in only one
direction of travel and are suitable for air-fail close and air-fail to open
applications without modification. These models are available with a
spring end torque between 2 Nm (20 lbf.in) and 2394 Nm (21000 lbf.in)
Safety Function:
For spring-return models, the safety function is self-evident performed by the
springs. The safety function of double-acting models should be performed by the
A-chamber for safety related systems.
