Special flange version of the LKB butterfly valve that makes it easy to remove the valve body without needing to dismantle piping set-ups. This in turn makes it easy to undertake repair, service and replacement with a bare minimum of disruption. Reliable performance LKB-F 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-F 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.
