The ThinkTop Basic Intrinsically Safe is designed to control the fluid handing process in hygienic applications across the dairy, food, beverage, biotechnology, pharmaceutical and many other industries.

• Reliable valve sensing and control
• Proven and inherently safe design
• Low total cost of ownership
• Watertight design
• Easy to operate

The ThinkTop Basic Intrinsically Safe valve sensing and control unit consists of a proven NAMUR feedback sensor system with light-emitting diodes (LEDs), low voltage solenoid valves, ready for connection to a electrical barriers and to any programmable logic controller (PLC) system with a digital interface. It fits on all Alfa Laval hygienic valves; no adaptor is required.

By an indication pin mounted on the valve stem, the NAMUR feedback sensors detects valve stem movement, the position of the valve at any given time, with the adjusted accuracy of the feedback sensors.

The Alfa Laval ThinkTop Basic Intrinsically Safe is fitted with up to two solenoid valves that can convert compressed air and the electrical PLC signal into mechanical energy to activate or deactivate the pneumatic valve actuator.
