Short overview of cms pneumatic air valves( VN and LV series)
The main task of these electromotors class is to provide good isolation during a possible explosion inside system. For this, all electrical elements are placed in a special shell. It is able to withstand high pressure that appears from the blast wave.
Transducers with closed-loop system are designed to create a compensation current in the secondary coil. That allows to create special flux, which is measured by operation of Hall generator.
