Alfa Laval Inditop: Reliable Valve Position Feedback for Hygienic Applications
The Alfa Laval Inditop is a digital valve indication unit designed to provide reliable, cost-effective operation for automated sensing of hygienic valves. It delivers real-time, precise information about valve operating status, boosting productivity while ensuring traceability. The IndiTop offers a streamlined and compact design that supports continuous production and maximum hygiene in challenging environments. 

Features

• Operates on a no-touch, set-and-forget sensory system, ensuring ease of use and minimal maintenance. 

• Ideal for both new and existing plants, the unit is compatible with all major PLC systems with a digital PNP/ NPN interface. 

• Easy to install with a five-button startup sequence or optional remote control wire function. 

• IP66/IP67-compliant, ensuring wateright operation. The unit can be housed down with water or cleaning fluids without compromising performance, promoting maximum hygiene. 

• Available in three cable length options ( 5M, 10m, 0.5m) to suit various installation needs. 

• M12, 5-pin stainless steel plug connector ensures a secure connection to the PLC system. 

 

Why choose Inditop 

• The LED indicator provides accurate, real-time feedback on valve position and status, enhancing operational efficiency. 

• The no-touch sensor system ensures minimal manual intervention and reduces the need for frequent adjustments, contributing to higher productivity. 

• Simple installation and easy-to-program setup make IndiTop a user-friendly solution for valve position monitoring. 

• The robust design withstands harsh conditions such as physical impact, pollution, and extreme temperatures, providing long service life. 

 

How it works 

The IndiTop uses a no-touch, set-and-forget sensory system that calculates the angle between the axial magnetic field produced by an indication pin mounted on the valve stem. This provides a highly accurate valve position reading of ± 1mm. 

• The sensor system detects the magnetic field generated by the valve stem and transmits the position data to the PLC. 

• The LED indicators show the current valve position and on/off power status at all times. 

• IndiTop transmits digital feedback signals (PNP/NPN) to the PLC system, ensuring clear communication and precise control. 

 

Applications

• Hygienic industries such as dairy, food, and beverage processing. 

• Biotechnology and pharmaceutical industries. 

• Automated valve control systems in sanitary applications

• Existing and new plants requiring continuous valve position monitoring.
