<p>The pneumatic amplifier has an air supply valve (9) with a supply inlet (13) connected to a pneumatic supply. A signal input (29) is provided for receiving a pneumatic input signal (P-S), and a signal output (57) is provided for transmitting an amplified pneumatic output signal (P-A). An outside (25) of an air supply valve diaphragm (23) is exposed to the amplified pneumatic output signal. The outside of the air supply valve diaphragm is averted to the signal input. An independent claim is included for an arrangement for positioning a regulating armature, for e.g. a control valve of a technical process system.</p> |
