LKB Butterfly Valve
The Alfa Laval LKB Butterfly Valve is a reliable, hygienic in-line valve for routing low- and medium-viscosity liquids in stainless steel pipe systems due to its substantial opening area and low flow resistance. Choose between manual or automatic operation using either a standard handle or pneumatic actuator. It is widely used in hygienic applications across the dairy, food, beverage, brewery and many other industries.
Reliable, cost-effective butterfly valve for flow control in piping systems across various hygienic applications
- High-performance, low flow resistance shutoff valve ensures high Kv value and low pressure drop
- Maintenance-friendly thereby minimizing service downtime, especially for the flange version
- Cost-effective solution for straightforward flow control
- Space-saving, economical construction facilitates inline mounting in piping systems
- High process hygiene due to the use of the same components as the EHEDG-certified LKB valve
Get reliable, cost-effective flow control and lift your process performance with the Alfa Laval LKB Butterfly Valve range. Minimal flow restrictions allow the unobstructed passage of process fluids, including those with high concentrations of particles. Easy to configure and upgrade, the LKB raises product quality while reducing energy, water and cleaning media costs, especially in combination with the Alfa Laval ThinkTop V50 and V70 pulse seat clean function.
Optimize flow control and quickly bring valves online using optional intelligent valve control units with auto-setup function. Maintenance is fast and economical; no special tools are required when replacing a single long-life component.
Versatile, modular, and easy to configure, these hygienic butterfly valves lift productivity and end-product quality across the dairy, food, beverage, brewery and many other industries.
Full range, full spectrum
The Alfa Laval LKB butterfly valve range consists of modular units designed to meet the full spectrum of requirements at working pressures from full vacuum to 10 bar. All valves are FDA-compliant, designed for use in a wide range of stainless steel pipe systems, and can be built to comply with virtually any installation standard.
Reliable performance
LKB butterfly valves come with several features that ensure reliability performance. A highly polished stainless steel disc with surface smoothness down to Ra<0.8 µm and bearing bushes clipped onto the disc stems prevent metal-to-metal abrasion and ensure smoother disc movement.
The stem diameter provides particularly low flow resistance, ensuring gentle product treatment for low and medium-viscosity products. In addition, Alfa Laval seal technology provides greater thermal stability, better chemical resistance and improved tensile strength.
Manual or automated control
Alfa Laval LKB butterfly valves can be complemented with lockable handle for manual operation of with an actuator and in combination with either a valve indication unit or Alfa Laval ThinkTop valve sensing and control units.
For manual operation: Alfa Laval provides a complete range of handles, including a multi-position lockable handle.
For automated operation: A selection of different actuators is available; special double-spring design enables application of maximum torque to the valve disc at breakaway and seal positions. This makes it easy to integrate these valve units into larger systems operated from a central point, and/or to operate them automatically for maximum efficiency.
How it works
The Alfa Laval LKB Butterfly Valve operates either by means of a pneumatic actuator from a remote location or manually 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 pneumatic operation, an actuator converts axial piston motion into a 90° rotation of the shaft. The actuator torque increases as the valve disc comes into contact with the butterfly valve seal ring 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 butterfly valves can also be mounted with indication units for feedback on the valve position (open/closed).
Save water with ThinkTop
Do something good for the environment and save up to 95% in CIP liquid when cleaning your valves. Innovations like ThinkTop sensing and control units make more efficient use of resources while safeguarding process hygiene. Add ThinkTop to your valves to optimize your processes.
