Removal, installation and adjustment of the drive of a butterfly valve

The drive of gas is very sensitive to excesses. Therefore at installation it is necessary to handle with it very with care. The excess can lead to break of a cable subsequently. Therefore the cables having excesses should not be put.

The cars having automatic adjustment of speed of the movement "Tempostat" for the lever of a butterfly valve have an additional drive of gas. If it is necessary, it is disconnected to similarly ordinary drive of gas.

The diesel engine 320d has no gas drive. Position of the accelerator pedal is transmitted to a control system through the pedal sensor.
