Specification
EMP-5
The EMP-5 series actuators provide damper control or valve control where it is desirable to move the crank
arm in either direction, or to stop it at any point in the stroke with a voltage or current input. These actuators
are NEMA Type 4.
Ambient Temperature
-40 °F to +136 °F (-40 °C to + 58 °C)
Note: Surface temperature during
normal operation can reach 40 °F
above ambient.
