Easy to configure and easy to upgrade, Alfa Laval butterfly valves contribute to high plant performance and high product quality.
How do butterfly valves work?
Alfa Laval butterfly valves can be operated either by means of a pneumatic actuator from a remote location or manually operated by means of a handle. The actuator comes in three standard versions: normally closed (NC); normally open (NO); and, air/air activated (A/A).
For automatic operation, a pneumatic actuator converts the motion of the axial piston into a 90° rotation of the shaft. The actuator torque increases as the valve disc comes into contact with the seal ring of the butterfly valve to secure proper closing of the valve seat.
For manual operation, a handle mechanically locks the valve in open or closed position. Two-position, four-position, regulating 90°-position, and multi-position handles are available. Manual valves can also be mounted with indication units for feedback on the valve position (open/closed).
Options for superior flow control, hygiene, durability and reliability of Alfa Laval butterfly valves include automation units with built-in actuators or smart valve control systems.

With its robust, straightforward construction, the leakage detection valve easily withstands harsh operating conditions, ensuring reliable operation, long service life and a low total cost of ownership.
How does the Leakage Detection Butterfly Valve work?
With its double block-and-bleed design, the Alfa Laval Leakage Detection Butterfly Valve ensures the separation of two products. In closed position, the valve disc creates two sealing points with an intermediate space between them. This space forms a leakage chamber at atmospheric pressure under every operating condition. If leakage occurs, the product flows into the drain through the outlet connections at the bottom of the valve for easy detection. When the valve is open, the leakage chamber is closed, and the product flows from one line to the other.
The valve can be operated either by a pneumatic actuator from a remote location or manually using a handle. The actuator comes in three standard versions: normally closed (NC); normally open (NO); and air/air activated (A/A).
For pneumatic operation, an actuator converts axial piston motion into a 90° rotation of the shaft. The actuator torque increases as the valve disc meets the valve seal ring to secure the proper closing of the valve seat. For manual operation, a handle mechanically locks the valve in an open or closed position. Manual valves can also be mounted with indication units for feedback on the valve position (open/closed).
