DDD Series Direct Coupled Actuators are non-spring return actuators that are perfect for positioning of dampers and valves in HVAC
systems. Actuators are designed to accept 4 to 20 mA or 0 to 10 VDC
modulating control signals and are 24 VAC powered. Actuators produce 88 to 265 in-lb (10 to 30 Nm) of torque. Unit features a 0 to 10
VDC feedback signal of damper position.

MAINTENANCE
Upon final installation of the Series DDD Non-Spring Return Direct
Coupled Actuator, no routine maintenance is required. A periodic
check of the system calibration is recommended. The Series DDD
is not field serviceable and should be returned if repair is needed
(field repair should not be attempted and may void warranty). Be
sure to include a brief description of the problem plus any relevant
application notes. Contact customer service to receive a return
good authorization number before shipping.
