Alfa Laval ThinkTop V20
Sensing and control
The Alfa Laval ThinkTop V20 valve indication unit offers reliable, cost-effective operation of hygienic valves. It provides standard functionality for intuitive sensing of the valve position and status, displayed on the unit’s 360° light-emitting diodes (LEDs). It also provides convenient real-time valve position monitoring and easy access to historical data, making process control more reliable and accurate while saving time and money on installation, commissioning, operation and maintenance.
Purpose-designed to digitalize essential on-off valve monitoring, the ThinkTop V20 is the first pure valve-sensing device that is maintenance-free and does not require manual adjustment or programming. It meets standard process system requirements for sensing and displaying the fluid handling status. It senses and indicates the valve position and status in fluid handling processes in hygienic applications across the dairy, food, beverage, home and personal care, biotechnology, pharmaceutical and many other industries.
- More reliable real-time process control from a sensor system that does not require readjustment over time
- 70 % faster, more intuitive setup than conventional valve indication units
- Compact, aesthetic and maintenance-free design based on the ThinkTop V-series
- Choice of communication protocols – digital, AS-I and IOLink – to suit process requirements
- 360° LED visual status indication, visible from all directions
The ThinkTop V20 is suitable for use on all Alfa Laval hygienic valves. Installation is efficient and straightforward; no expertise, adapter or special tools are required. Mount the unit on top of the valve, then tighten the two screws on the valve mushrooms. Plug the M12 female plug into the ThinkTop V20 to begin the intuitive live startup sequence. No additional steps are required. It is compatible with any Alfa Laval hygienic valve with standard mushroom connections, making it easy to install new or replace older valve indication units.
The ThinkTop V20 is an automated valve indication unit that does not require the use of any solenoid valve. It transmits the status and condition of the valve position to any programmable logic controller (PLC) system using electrical feedback signals, such as digital, AS-Interface or IO-Link. Light-emitting diodes (LEDs) on the unit provide a 360° visual indication of the valve status, visible from any direction, displaying the current main valve position and any local faults.
The sensor system accurately detects valve stem movement and the valve position at any given moment, using microchip sensors with an accuracy of ±1mm. Sensor chips on the sensor board calculate the angle between the axial magnetic field produced by a sensor target mounted on the valve stem to signal the current valve position. The ThinkTop V20 is compatible with all Alfa Laval hygienic valves, eliminating the need to readjust the sensors and thereby boosting productivity
