ST SmarTrak Controller is used as a positioning system for proportionally-driven hydraulic actuators with up to two independent channels. Fast stroke and superior resolution allow the unit to be used with severe service hydraulic actuators which demand fast stroking and precise positioning.

This product covers a wide range of actuator sizes and stroke length requirements and it is able to manage two fully independent actuators (moving two different valves).


  • High flow with quick, precise and complete control capability
  • No need for an amplification device in most applications
  • Powerful self calibration software with the ability to totally personalise the parameters
  • Robust design with a full metal housing
  • Superior control capacity of amplification device when installed
  • Wide set of configurable embedded features
