MicroTorque Precision Electric Rotary Actuator
Brand: MicroMod Automation & ControlsThe MicroTorque electric rotary actuator is designed to provide high resolution, high-accuracy positioning for valves and dampers. It continuously monitors and compensates for actuator backlash, motor coast, and load changes to eliminate positioner deadband. The 0.2 degree resolution stabilizes the process by preventing oscillation resulting in cooler motor operation, reduced wear on valve seals and stem packing, and lower maintenance costs.
The patented control circuitry allows the MicroTorque actuator to bridge the gap between the larger, high priced actuators and the less accurate economy models. The pulsed modulation control prevents thermal overload while providing excellent torque and response time.
