Unique Control for Butterfly Valve

 
Concept
LKBuniqueUnique Control for butterfly valves is an actuator with integrated automation for all sizes of LKB butterfly valves. Unique Control is a hygienic, reliable solution with focus on simplicity.
The Unique Control is a compliment to our existing range of actuators and control units and it provides the opportunity to upgrade 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 by a one bottom push perform a self configuration involving valve size recognition as well as calibration to the provided operating air pressure. 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 above one million strokes.
The Unique control has a 360 deg. indication light for visual status. It also provides the opportunity to monitor status of the operating air pressure identifying air leakage or failing air pressure.
