D-3153-3 Johnson Controls Damper Actuator

Overview

The Johnson Controls D-3153-3 is a pneumatic piston damper actuator featuring a 5 to 10 psi spring range and a 3-inch stroke. It serves as a multipurpose positioning device designed to operate ventilating dampers in response to output signals from a pneumatic controller or electro-pneumatic transducer.

Features

• Lightweight, non-combustible all-aluminum housing
• Telescoping piston rod for flexible linkage up to 8-3/4 inches away from the actuator face
• 2-way swivel head connection on the cylinder head for non-binding movement and full power delivery
• Swivel ball joint and slotted crank arm connector included for versatile installation options

Specifications

• Stroke: 3 inches (76 mm)
• Spring Range: 5 to 10 psi (35 to 70 kPa)
• Control Air Pressure: 0 to 20 psig for normal HVAC, 20 psig minimum for safety functions, 30 psig maximum
• Diaphragm Area: 15 square inches
• Air Connections: 1/8 inch NPT straight barbed fitting
• Materials: Die-cast aluminum body with a synthetic elastomer diaphragm
• Operating Temperature: -20 to 150°F (-29 to 66°C)
• Output Force (at 20 psig supply): 150 lb power stroke force and 75 lb return spring force

Applications

• Primarily used for operating ventilating dampers in commercial HVAC systems
• Suitable for proportional volume control on dampers up to 16 square feet and two-position actuation on dampers up to 25 square feet
• Designed for use with VAV control dampers, inlet vanes, and Johnson Controls safety dampers
