Alfa Laval ThinkTop Basic® Intrinsically Safe

Introduction

The Alfa Laval ThinkTop® Basic Intrinsically

Safe is a modular, explosion-safe automated valve control unit

that offers cost-effective operation and standard functionality for

automated sensing and control of hygienic valves. It provides real

time information about valve operating status 24/7 while

boosting productivity.

Application

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.

Benefits

• Reliable valve sensing and control

• Proven and inherently safe design

• Low total cost of ownership

• Watertight design

• Easy to operate

Standard design

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.

Working principle

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.
