Input signal Output pressure
When the input signal rises, the air supply solenoid valve q turns ON, and the exhaust solenoid valve w turns OFF. Therefore,
supply pressure passes through the air supply solenoid valve q and is applied to the pilot chamber e. The pressure in the pilot
chamber e increases and operates on the upper surface of the diaphragm r.
As a result, the air supply valve t linked to the diaphragm r opens, and a portion of the supply pressure becomes output
pressure.
This output pressure feeds back to the control circuit i via the pressure sensor u. Here, a correct operation functions until the
output pressure is proportional to the input signal, making it possible to always obtain output pressure proportional to the input
signal.
