ky Alfa Laval ThinkTop® D30 Digital
Leave Surveillance to the Top
Concept
The ThinkTop D30 is a basic valve control unit that consists of a
proven no-touch sensor system with 360-degree LED visual indication,
an integrated solenoid valve for spring-loaded actuator, and valve
control sensor board for connection to any PLC (Programming Logic
Controller) system with digital interface.
ThinkTop D30 offers a simplify solution for Alfa Laval butterfly and
single-seat valves and is designed for use in the dairy, food and
beverage, and biopharm industries; ThinkTop D30 is a supplement,
alternative solution to optimize applications instead of using external
solenoid valves and the existing range of control units.
Working principle
ThinkTop D30 fits onto nearly all Alfa Laval hygienic actuators equipped
with mushrooms. Installation is straightforward; no special expertise,
adapters or tools are required. ThinkTop D30 is an easy-to-use plug ‘n
play control unit with one 3/2-way solenoid valve and with integrated
intelligence to monitor the status of the operating air pressure,
identifying air loss or leakage. By getting the electrical PLC and sensor
signals the integrated solenoid valve enables control of the processing
valve by open or closing the air-operated valve.
