How does sensing and control work?
Alfa Laval valve automation solutions include advanced ThinkTop sensing and control units and cost-effective indication units to meet different process requirements.
Compatible with all Alfa Laval valves, the Alfa Laval ThinkTop series uses microchip sensors for precision measurement of the valve stem movement and valve end positions.
Digital PNP feedback signals, AS-Interface, or IO-Link communication protocol connect sensors and actuators, regardless of fieldbus, to your automation systems. Collecting, storing, analyzing meaningful real-time data brings the power of Industry 4.0 to your hygienic processing lines.
Mounted directly on the valve top or the valve yoke, Alfa Laval indication units feature up to two feedback signals that show the valve position (open or closed). Operating principles vary, depending on the sensor type, including non-contact proximity sensors, two- or three-wire proximity sensors, and sensors with M12 plug or encapsulated cable.

How it works
The Alfa Laval ThinkTop V40 control unit provides a single-sensor solution for butterfly and single seat valves. Equipped with one solenoid valve, it converts electrical PLC output signals into mechanical energy to energize or de-energize the air-operated valve using the physical sensor target mounted on the valve stem.
Installation with Live Setup is fast and straightforward. Simply activate the manual override on the solenoid valve to initiate the Live Setup sequence. The ThinkTop automatically recognizes the type of valve and completes the programming. Alternatively, setup can be performed remotely from a PLC using the remote Live Setup function – without dismantling the control head.
