VFBV240 VFBV2/VFBV3 - 2- and 3-way ball valves
Ball valves, DN15-50, kvs 0.6-63, designed for control of hot, cold or glycol-mixed water in heating and ventilation systems. These ball valves can be used as either characterized control ball valves when a flow plate is installed in port A (default mode), or as on/off ball valves when the flow plate is removed. When the flow plate is removed the Kvs between port A and AB is increased. To be coupled to SEB4 / SEB5 actuators.
