           Proportional Regulator
           The A17 is a 3/2 proportional regulator with a
           6mm valve. The regulator is designed to match
           a controlled pressure output with an electronic
           signal input. It is used to control fast and slow
           pressure steps, ramps and curves, in both
           rising and falling directions.
