Hoe het werkt


The Alfa Laval ThinkTop V50 and V70 valve control units offer a single-sensor solution for butterfly, single-seat and mixproof valves; a single control unit can be fitted with up to three solenoid valves. ThinkTop 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 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.
