Exploit the power of IO-Link

Demand more from your valves with the Alfa Laval ThinkTop IO-Link. The ThinkTop IO-Link enhances communication between your hygienic valves and Industry 4.0 automation systems. The point-to-point IO-Link communication protocol connects sensors and actuators, regardless of fieldbus, to your automation systems. This makes meaningful real-time data easier to capture, store, analyze and act upon.


  • Enhanced flexibility which lets you change data parameters and process data from a remote automation system
  • More uptime and less cost due to 24/7 data monitoring and diagnostics
  • Comprehensive overview of data for timely preventative maintenance and optimized performance
  • Clearly visible LEDs with customizable colours and a 'wink' function that makes it easier to locate a valve from the factory floor
  • Greater water and wastewater savings

How it works 

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.


Pulse seat clean: cut CIP liquid consumption on drain valve cleaning by up to 95%

Drain valves comprise 20% of all valves in typical process plants. Imagine the water savings you can realize by adding the Alfa Laval ThinkTop pulse seat clean to your drain valve cleaning process.

In less than a second, an intensive jet of CIP liquid pulses through the gap between the valve house and valve seat, creating high turbulent flow and leaving the valve spotless. The result? Quick and effective cleaning, more uptime, and increased end-product yields.
