Working Principle
When the input signal rises, the air supply soloenoid valve q turns ON. Due to this, part of the supply pressure passes through
the air supply solenoid valve q and changes to output pressure. This output pressure feeds back to the control circuit r via the
pressure sensor e. Here, pressure corrections continue until output pressure becomes proportional to the input signal, enabling
output pressure that is proportional to the input signal.
