Description

Butterfly valves are relatively straightforward on/off routing valves with a substantial opening area and low flow resistance. Where hygiene standards are important, these are ideal for use with low and medium-viscosity liquids. 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. Product Benefits

How it works Construction The valve consists of two valve body halves, valve disc, bushes for the stem and seal ring. The valve is assembled by means of screws and nuts. The handle is fitted onto the valve by means of a cap/block system and screw. Operating principle The standard Alfa Laval LKB butterfly valve range is designed either for automatic or manual operation. Automatic operation for LKB and LKB-F The automated LKB butterfly valve is controlled from remote location by means of compressed air using a pneumatic actuator. The actuator controls the axial movement of a piston, which rotates the shaft 90°. The torque exerted by the actuator increases when the valve disc contacts the valve sealing ring, to ensure effective closing. The actuator is available in three standard versions: normally closed (NC), normally open (NO) and air/air activated (A/A). Manual operation for LKB and LKB-2 The LKB butterfly valve is controlled manually by means of a handle. The handle mechanically locks the valve in its open or closed position. For the LKB and LKB-2, the handles for the valve sizes DN125 and DN150 enable valve adjustment and can be locked in two intermediate positions to regulate the flow rate. Part of a broad valve range Alfa Laval offers a comprehensive range of valves intended for hygienic applications in the dairy, food, beverage,home care, personal care, biotechnology and pharmaceuticals.
