Working Principle
The VT–1-23W-08-P-0 receives a control command from a PLC, DCS, or local input. It compares the commanded value with actual feedback from position, pressure, or force sensors. The internal control algorithm calculates the required valve drive signal and outputs an analog command to the proportional or servo valve. The hydraulic actuator moves accordingly, and the feedback signal is continuously monitored to correct deviations. Fieldbus communication allows parameter access, status monitoring, and integration into higher-level automation systems.
