Efficiently regulate the flow of low and medium-viscosity fluids with the double-flanged Alfa Laval LKB-F butterfly valve. Its substantial opening area and low flow resistance promote high productivity and yield. Compact, lightweight and robust, it is easy to install, align and service. It is widely used in hygienic applications across the dairy, food, beverage, brewery, and many other industries.
Reliable flow regulation, easy maintenance and higher productivity
- High Kv value and low flow resistance promote higher productivity and yield
- Quick and easy maintenance of this flanged LKB version minimizes service costs and downtime
- Economical 4-20mA flow regulation due to low capital investment costs and optimized valve operation
- Space-saving inline mounting that easily connects to the piping system
- High process hygiene due to the use of the same components as the EHEDG-certified LKB valve
Count on the double-flanged Alfa Laval LKB-F butterfly valve for the reliable flow regulation of low- to medium-viscosity processing fluids and those with high particle concentrations in hygienic applications. Flanges on both valve body ends make installation and alignment with the pipeline flanges effortless.
This high-performance, quarter-turn shutoff valve delivers solid performance and lifts productivity. Maintenance is economical and straightforward. Simply remove the valve body for scheduled wear part replacement. No special tools or dismantling of the piping system is required.
Choose the LKB-F raises product quality and yield while reducing energy, water and cleaning media costs, especially in combination with the Alfa Laval ThinkTop V50 and V70 pulse seat clean function.
How does the LKB-F butterfly valve work
Installation of the Alfa Laval LKB-F is straightforward, matching the two flanged ends on the valve inlet and outlet ports to the pipeline flanges in the piping system. It uses either a pneumatic actuator from a remote location for automated process control or a handle to regulate the flow manually. 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 butterfly valve’s 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. 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).
Maintenance is easy due to the two flanges and two flange seal rings, which make it easy to remove the valve body without disassembling the piping system. Optional valve sensing and control units provide intuitive control of the double-flanged LKB-F butterfly valve.
