Coupled Actuators (DCA) are used within heating, ventilating,
and air-conditioning (HVAC) systems. They can drive a variety
of quarter-turn, final control elements requiring spring return
fail-safe operation.
Applications include:
• Volume control dampers, mounted directly to the drive
shaft or remotely (with the use of accessory hardware).
• Quarter-turn rotary valves, such as ball or butterfly valves
mounted directly to the drive shaft.
• Linear stroke globe or cage valves mounted with linkages
to provide linear actuation.
• Available with cable on select models
