EP-8000-4 Johnson Controls ELECTRO Pneumatic Transducer

Overview

The Johnson Controls D-3153-6003 is a heavy-duty pneumatic damper actuator designed to precisely position ventilating dampers in commercial HVAC systems. Operating as a body-only configuration, this multipurpose linear positioning device reacts reliably to output signals from pneumatic controllers or electro-pneumatic transducers. It features a rugged design intended for long-lasting service in demanding building automation environments.

Features

• Body-only configuration allowing flexible field assembly and replacement.
• Incorporates a 2-way swivel connection on the cylinder head to ensure non-binding movement and full power delivery.
• Utilizes a fail-safe spring return system to ensure dependable positioning during power or signal interruptions.
• Equipped with an all-aluminum housing that provides a lightweight yet non-combustible protective enclosure.
• Designed with telescoping linkage to simplify and accelerate installation across various damper configurations.

Specifications

• Spring Range: 8 to 13 psi nominal spring range for accurate air flow modulation.
• Stroke: 3 inches (76 mm) providing broad damper travel.
• Control Air Pressure: 0 to 20 psig (0 to 138 kPa) for standard HVAC operation; maximum pressure up to 30 psig (207 kPa).
• Diaphragm Size: Large 15-inch effective diaphragm area providing high actuating force.
• Air Connection: 1/8 inch NPT straight barbed fitting.
• Body Material: Heavy-duty die-cast aluminum.
• Ambient Operating Temperature: -20 to 150°F (-29 to 66°C).

Applications

The D-3153-6003 is ideal for controlling airflow within commercial and industrial HVAC systems, including air handling units, VAV terminals, and mixed-air damper assemblies. It is rated to operate dampers up to 16 sq ft for proportional volume control and up to 25 sq ft for two-position actuation, provided torque requirements align. The actuator is suitable for pairing with safety dampers and accommodates standalone or slaved multi-damper setups.
