Product Description

D-3153 Pneumatic Actuator

The D-3153 Pneumatic Actuator is a multipurpose positioning device used primarily for operating ventilating dampers in response to the output signals of a pneumatic controller or electro-pneumatic transducer. The D-3153 can be used with dampers up to a maximum area of 16 square feet for proportional volume control and 25 square feet for two position actuation provided that the torque requirements are compatible with the     specific application. The D-3153 is UL component recognized for use on UL classified 555/555S smoke and combination fire/smoke dampers which have been tested and approved to a degradation temperature of 250°F

Air pressure from a pneumatic controller is applied to the diaphragm of the actuator, which moves the piston against the forces of the internal spring and the load. The external load force shifts the operating range from the nominal spring range. The piston will move to a position where the applied force and the spring plus external forces are in equilibrium. However, with a pilot positioner added, the piston will move to a position proportional to the control signal regardless of the load.

Repair Information
Field repairs cannot be made. Unit must be replaced
