5 Compact Electro-pneumatic Regulator Series ITV 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 product 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 Series ITV/2/3 Working Principle 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.

(Set pressure) y Atmospheric pressure valve Working Principle When the input signal increases, the vacuum pressure solenoid valve q turns ON, and the atmospheric pressure solenoid valve 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. As a result, the vacuum pressure valve 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.

Connect the vacuum pump to the port, which is labeled VAC. 2. Pressure adjustment changes from atmospheric pressure to vacuum pressure when the input signal is increased, and from vacuum pressure to atmospheric pressure when the input signal is decreased. 3. When adjusting the vacuum pressure, be careful not to block the atmospheric pressure inlet port labeled ATM. 4. Since this product is designed exclusively for use with negative pressure, be careful not to apply positive pressure in error. 5. In cases where the vacuum pump being used has a relatively small capacity, or the piping has a small inside diameter, etc., large variations in the set pressure (the range of pressure variation when changing from no flow to flow state) may appear. In this situation, the vacuum pump or the piping, etc. should be changed. In cases where it is not practical to change the vacuum pump, install a capacity tank (volume depending on the operating conditions) on the VAC side. 6. The vacuum pressure response time after a change in the input signal is influenced by the internal volume on the setting side (including piping). Since the capacity of the vacuum pump also influences the response time, give careful consideration to these points before operation. 7. If the electric power is shut off when in a control state, the pressure on the setting side will go into a holding condition. However, this setting side pressure will be held only temporarily and is not guaranteed. In addition, when atmospheric pressure is desired, shut off the power after reducing the set pressure, and then introduce atmospheric pressure by using a vacuum release valve, etc. 8. If the power for this product is cut off by a power failure, etc. when it is in a controlled state, the setting side pressure will be held temporarily. Further, if operated without sealing the setting side so that atmospheric air is sucked in, handle with care as air will continue to be sucked in Precautions L-bracket Be sure to read before handling. Refer to pages to for Safety Instructions and Common Precautions. Handling 25 5 () (7) R ø If the VAC side pressure to this product is interrupted while the power is still on, the internal solenoid valve will continue to operate and may cause a humming noise. Since this may shorten the life of the product, be sure to shut off the power when the VAC side pressure is shut off.. The setting side pressure cannot be completely released from this product in the range below.3 kpa. In cases where the pressure needs to be reduced completely to kpa, install a 3 port valve, etc. on the setting side to discharge the residual pressure.. This product is adjusted for each specification at the factory before shipment. Avoid careless disassembly or removal of parts, as this can cause failure. 2.
