3.1 General information
Concept
Unique Control for butterfly valves is an actuator with integrated automation for LKB butterfly valves. Unique Control is a
hygienic, reliable solution with a focus on simplicity.
The Unique Control complements our existing range of actuators and control units and it provides the opportunity to upgrade an
existing installation.
Unique Control is compatible with all major PLC systems. It is for use in food, dairy and brewery installations and in
biopharmaceutical applications.
Working principle
The Unique Control uses an air spring allowing operation at a significantly lower air pressure compared to a conventional
mechanical spring. The integrated intelligent automation will self-configure and calibrate with a single press of a button. The
actuator is designed for easy onsite configuration as either normally open (NO) or normally closed (NC). The maintenance-free
but serviceable actuator design is tested to perform over one million strokes
The Unique Control has a 360 deg. indication light for visual status.
It also provides the opportunity to monitor the status of the operating air pressure, identifying air leakage or failing air pressure.
