D-3153-4 Johnson Controls Damper Actuator

Overview

The Johnson Controls D-3153-4 is a heavy-duty pneumatic damper actuator designed primarily for positioning ventilating dampers in commercial HVAC and building automation systems. Operating in response to pneumatic signals, it incorporates a 15-inch diaphragm and a die-cast aluminum housing to deliver high force output and reliable performance in demanding air-handling environments.

Features

• Heavy-duty die-cast aluminum housing providing a lightweight, non-combustible design.
• Large 15-inch synthetic elastomer diaphragm for high force output.
• Two-way swivel connection on the cylinder head ensuring full power delivery and non-binding movement.
• Telescoping piston rod enabling fast and flexible linkage installation.
• Integrated D-9502 pilot positioner for precise sequential operation and accurate positioning regardless of load.
• Companion auxiliary mounting bracket included for adaptable installation configurations.

Specifications

• Model: D-3153-4
• Brand: Johnson Controls
• Nominal Spring Range: 8 to 13 PSI
• Stroke Length: 3 inches (76 mm)
• Control Air Pressure: 0 to 20 PSIG for normal HVAC operation; 20 PSIG minimum for safety damper functions; 30 PSIG maximum pressure

Applications

The D-3153-4 is ideal for regulating airflow within variable air volume (VAV) systems, air handling units, and generalized commercial heating, cooling, and ventilation applications. It is frequently employed where tight airflow control or heavy-duty actuation is required to safely adjust large or multi-blade control dampers.
