D-4073 Pneumatic Actuator
The D-4073 Pneumatic Actuator is a multipurpose
positioning device used to accurately position small
dampers primarily on unit ventilator, Variable Air
Volume (VAV), terminal units, and small ventilating
dampers in response to output signals of a pneumatic
controller or electro-pneumatic transducer.
The actuator is also recommended for use on other air
flow control dampers, in interior locations, up to a
maximum area of 6.75 square feet for proportional
volume control and 11.7 square feet for two position
actuation provided that the torque requirements are
compatible with the specific application.
The D-4073 is a direct replacement for existing
D-3073 actuators and a functional replacement for
former D-251 actuators.
