Description
The solenoid actuator MB 7 serves as a drive for the butterfly valve BVHM. The unit made up of solenoid actuator MB 7 and butterfly valve BVHM can be used for staged control of industrial installations in cold or hot air operating mode.
The position of the valve can be read on the valve disc position indicator on the outside of the MB 7. The low and high fire is easily configurable by adjusting two hexagonal nuts. In the event of a mains voltage failure, the MB 7 closes the butterfly valve.
Due to the large number of operating cycles of solenoid actuator MB 7, it is ideal for intermittent and pulse firing operations.
