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 V70 valve control units offer a single-sensor solution for butterflysingle-seat and mixproof valves; a single control unit can be fitted with up to three solenoid valves. 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.

Installation with auto setup is intuitive and fast. To initiate auto setup, simply press the “Select” button and then the “Enter” button to begin the setup sequence. The process is completed in accordance with the number of solenoid valves fitted to the control unit. Alternatively, the ThinkTop valve control unit can be set up without dismantling the control head using the built-in “Live setup” feature for remote configuration.

Burst seat clean: sustainable water savings for mixproof valve cleaning systems

Save up to 90% of the Cleaning-in-Place (CIP) liquid used for mixproof valve cleaning with the Alfa Laval ThinkTop burst seat clean. Unlike conventional PLC timer-based seat lift cleaning, burst seat cleaning uses minimal water and cleaning media. In less than a second, high-impact bursts of CIP liquid effectively clean your mixproof valves, removing all residuals from seat surfaces and safeguarding process hygiene.

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.
