The CENTORK Linear actuators are suitable for the actuation of valves with a linear movement (Globe, gate or diaphgram valves) where a high accuracy is needed or where the valve allows only a linear actuation.

With the integration of a multiturn actuator and a LC linear thrust unit, that converts the multiturn movement into a linear one, a linear and self-locking movement with a wide range of output speeds.

Both 460/470 series Digital actuators and 400/410 series electromechanical actuators can be used in combination with the suitable LC linear thrust unit.

The 400 or 460 series actuators can be completed with different Centronik control options and with different combinations of switching and signalling options to cover a wider range of applications.

Through the use of the suitable multiturn actuators series (400 or 410;460 or 470), both On/Off or Modulating options can be supplied.

Main characteristics:
