Valve Limit Switches & Positioners
 
Alfa Laval Indication Units for LKB/LKLA, SRC, ARC and ARC-SB Sanitary Valves:
Micro Switch A micro switch can be compared with a standard light switch but in a very small size and light in weight, a so-called subminature switch. It is activated mechanically by a roller leaf. Inductive Proximity Switch This type of switch is a non-contact electronic switch. It consists of an oscillator which creates high frequency electromagnetic fields which radiate from the sensing face of the switch. Hall Proximity Switch Hall proximity switches are also non-contact electronic switching elements. The sensor registers a magnetic field (north pole) and consists of a Hall element (a type of a transistor) matching part, an amplifier and an output part. View Alfa Laval Indication Unit Brochure 
Alfa Laval ThinkTop Control and Indicator System
The ThinkTop range of valve-top units can be used to control and monitor any air-operated sanitary valve from Alfa Laval – including single-seat, butterfly and mixproof sanitary valves. They are designed to ensure low cost of ownership in every aspect of valve operation, along with reliable, accurate control of what happens and when. ThinkTop units provide reliable, real-time data about the valve's operating status, helping pave the way to full traceability for each production batch. Automatic reporting about valve condition also helps prevent unscheduled – and costly – production stoppages. ThinkTop control and indicator units are easy to install and set up, either manually using a foolproof “5-push setup” method, or remotely from a PLC. No dismantling or adaptors are needed, thus saving both time and money. The combination of a patented “no touch” sensor system and preset tolerance bands means ThinkTop units are also self-adjusting.

Alfa Laval IndiTop Indication Unit
The IndiTop indication unit is a straightforward, easy-to-use electrical feedback unit for use with Alfa Laval sanitary valves. It can be set up either manually or via a PLC. The IndiTop valve indicator is designed to provide accurate, reliable information about the status of the many sanitary-standard valve units used in food, dairy and brewery installations and in biopharmaceutical processing. The IndiTop valve indicator fits onto all Alfa Laval actuated sanitary valves, as well as virtually all other kinds of valves fitted with actuator “mushrooms”. It uses the same technology for all types of valves and is easy to set up either manually or via a PLC. View Alfa Laval IndiTop Indication Unit Brochure  
GEA Tuchenhagen T.VIS® P-20 Positioner
 The T.VIS product range, available for the well-known VARIVENT® modulating control valve types A and S, now includes the T.VIS® P-20, the new positioner for VARIVENT® / ECOVENT® sanitary single seat and butterfly valves. For control loops in which a modulating control valve with a sophisticated positioner is too costly in terms of labor and time, GEA Tuchenhagen offers a cost-effective and economical alternative. Advantages of the T.VIS® P-20:

Gemu Electrical Position Indicators
GEMÜ provides a wide and well-balanced range of electrical position indicators to monitor linear and quarter turn sanitary valves. Dependent on the device type, either microswitches or proximity switches are used. They enable reliable end position feedback and can be equipped with a field bus connection upon request (e.g. AS-Interface, DeviceNet etc.). The new generation is self-learning. The devices recognize the valve end positions from the manual or automatic end position programming during initialization. No more work-intensive manual setting of microswitches or proximity switches is necessary; the breaking in of installations or recalibration after servicing work becomes considerably easier.
