3 General information
3.1 Concept
The ThinkTop D30 is designed to ensure valve control in a basic market, using Alfa Laval air operated actuators such as
butterfly, single and double-seat valves. it is compatible with all major PLC systems (Programmable Logic Controller) with a
digital PNP interface.
It is for use in food, dairy and brewery installations. ThinkTop D30 is a complementary, alternative solution to the existing
range of control units.
ThinkTop D30 is the first of its kind on the market that focuses on new methods to simplify all aspects of using a basic control
unit to minimise and optimise installations instead of using external solenoid valves
3.2 Working principle
The ThinkTop D30 is an easy-to-use plug ‘n play control unit with integrated intelligence which monitors the status of the operating
air pressure, identifying air leakage or failing air pressure. The integrated solenoid valve allows control of the processing valve.
Mounted on top of the valve, the unit receives signals from a PLC system to control the solenoid valve and it returns the
supervised air pressure signals for valve energised or de-energised feedback to the PLC system. The ThinkTop D30 has a 360
degree visual valve status indicator, which can be seen at a distance and at any angle.
3.3 Recycling information
• Unpacking
- Packing material consists of wood, plastics, cardboard boxes and in some cases metal straps
- Wood and cardboard boxes can be reused, recycled or used for energy recovery
- Plastics should be recycled or burnt at a licensed waste incineration plant
- Metal straps should be sent for material recycling
•Scrapping
- At the end of use, the equipment should be recycled according to relevant, local regulations. In addition to the actual
equipment, any hazardous residues from the process liquid must be considered and disposed of in a proper manner. When
in doubt, or in the absence of local regulations, please contact your local Alfa Laval representative.
