Motion Converter

MC Motion Converter is designed to efficently mount rotary positioners or accessories on linear actuators.

This product is available with an adjustable and changeable coupling kit to connect different positioners or accessories. The conversion from linear movement (actuator and valve stem) to rotary movement is made by a lever mechanism designed to minimize the linearity error, while the coupling kit is designed to avoid radial forces on the mounted positioners or accessories. 

This product removes the inaccuracy of a traditional system lever/pin arrangement. In a traditional feedback arrangement on vales with small stroke lengths, performances are lost due to the short linear stroke of the valve: this device avoid this problem.


  • Adaptable at every stroke in the field
  • Backlash recovery system
  • Maintenance free
  • Robust construction not affected by dust, ice, temperature and other contaminants
  • Self cleaning system
  • Significant reduction of the linearity error
