Series DDA & DDC Non-Spring Return Direct Coupled Actuator

Low Cost, Two-Position or Modulating

DDA and DDC Series Direct Coupled Actuators are non-spring return actuators that are perfect for positioning of dampers and valves in HVAC systems. DDA actuators are designed to accept floating control signals and come in a variety of power supplies. DDC actuators are designed to accept 4 to 20 mA or 0 to 10 VDC modulating control signals and are 24 VAC powered. DDC units feature a 0 to 10 VDC feedback signal of damper position. Actuators produce 17 to 70 in-lb (2 to 8 Nm) of torque. Contact factory for optional internal auxiliary switch on DDA.
