Improve the flow control of your LKB butterfly valves and maximize process hygiene with the Alfa Laval Unique Control LKB, a maintenance-free actuator integrated with an intelligent control unit. It controls the flow of processing fluids for any application that has stringent hygiene requirements.


The Unique Control LKB fits all manual and actuated butterfly valves in the Alfa Laval LKB range. This quarter-turn valve actuator enhances flow control for products with high viscosity, high particle content, or low air pressure requirements.


Setup is easy, enabling quick upgrades of manual or pneumatic shut-off valves – five times faster than conventional solutions. This straightforward automation solution. is suitable for use across the dairy, food, beverage, brewery and many other industries.

How it works

The Alfa Laval Unique Control LKB uses an air spring actuator, enabling operation at a significantly lower air pressure compared to control units using a conventional mechanical spring. Based on the operating air pressure, the actuator configures itself and calibrates values by pushing a single button. The actuator also monitors the operating air pressure and sends alerts if issues require attention to prevent malfunction, thereby ensuring more uptime.
