Control & Indication Units (ThinkTop Series)
Valve control units provide actuation control, position sensing, and clear status indication for hygienic valves. ThinkTop units simplify commissioning with intelligent setup and offer 360° LED visibility for fast, safe operation.
Overview
Control and indication units are essential for reliable hygienic valve automation. They provide accurate position feedback, robust control of solenoids, and clear, on-site visibility of valve status.
What a control unit does
- Indicates valve position and status via 360° LEDs.
- Controls valve actuation using integrated solenoid configurations (model dependent).
- Supports plant automation via Digital, IO-Link, or AS-Interface communication.
- Reduces commissioning time through automatic setup and valve recognition (V50/V70).
Typical applications
- Automated hygienic valve systems in dairy, food, beverage, pharma & biotech.
- CIP operations requiring seat lift sequences and reliable feedback.
- High-cycle production lines needing clear status and stable control.
- Retrofit projects upgrading older indication units with modern interfaces.

Selection checklist
Send these details so we can propose the right ThinkTop model, interface, and configuration.
Valve & actuator details
- Valve type (e.g., Unique SSV, Mixproof, DV-ST, Shutter, etc.)
- Actuator type (standard, long stroke, Air/Air, 2-step)
- Existing top unit / retrofit requirement (if upgrading)
- Solenoid requirement (0 / 1 / 2 / 3 and 3/2 or 5/2 where applicable)
Automation & process needs
- Preferred interface: Digital / IO-Link / AS-i (v2.1 or v3.0)
- Electrical connection preference: M12 or cable gland
- CIP needs: standard seat lift vs. Burst seat clean optimization (V70)
- Site compressed air connection preference: 6mm or 1/4"
Need a quick recommendation?
Tell us your valve type, actuator type, preferred interface (Digital/IO-Link/AS-i), and whether you need Burst seat clean (V70). We’ll recommend the correct ThinkTop model and configuration.
FAQ
Quick answers to common questions about ThinkTop control and indication units.
What is a valve control / indication unit?
It is a device mounted on the actuator that provides valve position feedback, visual status indication (LEDs), and (depending on configuration) control of solenoids for valve actuation.
What is the difference between ThinkTop V50 and V70?
V70 supports more advanced actuator configurations and includes the Burst seat clean function for CIP optimization. V50 is an advanced unit for standard actuator setups with automatic setup and valve recognition.
When should I select V20?
V20 is a reliable, cost-effective option when you need standard indication and status feedback with 360° LEDs, and you want simple installation and upgrade compatibility for older units.
Which interface should I choose: Digital, IO-Link or AS-i?
Choose based on your plant automation architecture. Digital is standard discrete I/O, IO-Link offers diagnostics and configuration, and AS-i supports networked nodes (v2.1 or v3.0 depending on system).
