6 Series ITV Working Principle When the input signal rises, the air supply soloenoid q turns ON. Due to this, part of the supply pressure passes through the air supply solenoid 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.

15 Electro-Pneumatic Regulator Series ITV// Working Principles When the input signal rises, the air supply solenoid q turns ON, and the exhaust solenoid w turns OFF. Therefore, supply pressure passes through the air supply solenoid 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 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.

33 Compact Vacuum Regulator Series ITV9 Working Principle When the input signal rises, the air supply soloenoid q turns ON. Due to this, part of the supply pressure passes through the air supply solenoid 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.

40 Series ITV9 Working Principle Working Principle Power supply Input signal q Vacuum pressure solenoid r Diaphragm Pressure display i Control circuit Output signal w Atmospheric pressure solenoid Atmospheric pressure u Pressure sensor e Pilot chamber When the input signal increases, the vacuum pressure solenoid q turns ON, and the atmospheric pressure solenoid w turns OFF. Because of this, VAC. and the pilot chamber e are connected, the pressure in the pilot chamber e becomes negative and acts on the top of the diaphragm r. As a result, the vacuum pressure t which is linked to the diaphragm r opens, VAC. and OUT. are connected, and the set pressure becomes negative. This negative pressure feeds back to the control circuit i via the pressure sensor u. Then, a correct operation works until a vacuum pressure proportional to the input signal is reached, and a vacuum pressure is obtained which is always proportional to the input signal.
