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 does the ThinkTop V50 work
The Alfa Laval ThinkTop V50 valve control unit offers a single sensor solution for Diaphragm valves, Butterfly valves and Single seat valves and it can be fitted with 0 or 1 solenoid valves. The ThinkTop valve control unit converts the 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.
Experience a seamless and speedy installation process with the Alfa Laval ThinkTop valve control unit's auto setup feature. To begin, just press the "Select" button, followed by the "Enter" button, and the setup sequence will initiate automatically. The process adapts according to the number of solenoid valves connected to the control unit. Additionally, if needed, you can perform a "Live setup" without disassembling the control head, enabling convenient remote configuration.
