Control valve based on standard type series BOA-C, BOA-CS, BOA-C EKB, BOA-Control IMS, single-piece pressure-retaining body with soft seat. Leakage rate selectable from 0.05 % to drop-tight at KVS values between 6.3 and 700 m3/h and closing pressures up to 16 bar. With intelligent microprocessor controlled electric actuators with actuating forces from 1200 N up to 14000 N, electronic configuration of valve characteristics, KVS value, control signal and time through PC tool or manual device. Customised configurations can be implemented by qualified KSB personnel at the factory.


Hot water heating systems up to 120 °C. Venting and air-conditioning systems, water supply systems. Drinking water. Not suitable for fluids containing mineral oils, steam or fluids liable to attack EPDM and uncoated cast iron. IMS not suitable for open circuits. Other fluids on request.
