Butterfly valves are relatively straightforward on/off routing valves with a substantial opening area and low flow resistance. This makes them the workhorse solution in modern processing technology, ideal for use with low and medium-viscosity liquids.       The LKB range of butterfly valves consists of modular units designed to meet the full spectrum of requirements at working pressures from full vacuum to 10 bar. A comprehensive range of features and equipment is available, with different versions to comply with any installation standards, worldwide. This means you can always find an LKB butterfly valve configuration to meet any specific requirement. The LKB range of stainless steel butterfly valves features a large opening area that results in particularly low flow resistance. This helps make sure that low and medium-viscosity products are treated gently. These valves also allow for reversible flow direction.   These valves can be fitted with vertically mounted LKLA actuators, as well as ThinkTop control and monitoring units. 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. For manual operation, Alfa Laval provides a complete range of handles, including a multi-position lockable handle and a complete range of multi-position, mechanically locking handles. Alfa Laval butterfly valves bear the LKB designation.
