Multiturn Linear Operation
   

 DC are superior when gatevalves must be operated, which are almost always used as shut off valves, and have therefore their highest torque peak in the “closed”- position.

Turning  or multi-turn actuators are often used for control valves, in which the body is designed to either increase or decrease the quantity  of flow through the valve.  DC motors react considerably faster when accelerating or braking.

Advantages of DC motors compared to AC motors

  • Torque performance is ideal for gate valves
  • Compact construction
  • Easier to implement in electrical systems
  • Low heat buildup
  • Low electricity consumption

 Particular benefits for control operations

  • Fast response
  • Exact positioning with the reverse electrical  brake
  • Precise positioning with high resolution of stroke movement
