How It Works
The Sipos Linear Electric Actuator converts rotary motor motion into linear thrust to operate valves that move along a straight axis.
Its intelligent control unit continuously monitors torque, position, and temperature, automatically adjusting motor speed to match load conditions.
With integrated fieldbus communication, operators can perform real-time diagnostics, remote configuration, and predictive maintenance.
