7 Therefore, supply pressure passes through the air supply solenoid valve (1) and is applied to the pilot chamber (3). The pressure in the pilot chamber (3) increases and operates on the upper surface of the diaphragm (4).As a result, the air supply valve (5) linked to the diaphragm (4) opens, and a portion of the supply pressure becomes output output pressure feeds back to the control circuit (8) via the pressure sensor (7). 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 Principle DiagramElectro-Pneumatic RegulatorSeriesITV2000/3000 ITV Series 2/18/99 4:37 PM Page 3 ITV201mPressure characteristicsFlow characteristicsLinearityHysteresisSet pressure (MPa)Input signal (% )Output deviation factor (% )Input signal (% )Output deviation factor (% )Supply pressure (MPa)Set pressure (MPa)Flow rate (l/min (ANR))Supply pressure: Set pressure.
