The Johnson Controls D-3244-4 pneumatic damper actuator is engineered to perform efficiently in various HVAC settings. Featuring a swivel pedestal mount, it facilitates easy installation while ensuring stability during operation. The actuator achieves a stroke length of 4 inches, providing sufficient movement to actuate dampers effectively.
This device operates within a control pressure range of 8 to 25 psi, with a minimum control threshold of 8 psi necessary for activation. It supports both normally closed and normally open valve actions, making it versatile for different system requirements. The air connection is designed for 1/8-inch NPT fittings, facilitating seamless integration into existing setups.
A synthetic elastomer diaphragm ensures reliable performance and durability under operational strain. The actuator can withstand harsh conditions, operating efficiently in temperatures from -20 to 150 degrees Fahrenheit. It should be noted that it does not include an integrated positioner but functions as a linear actuator, providing precise control in damper applications.
