Open the catalog to page 1Seven Features of the Vacuum Valve Original Solenoid Construction ① No burning damage to solenoid No need to stock solenoids as spare parts. ② Starting and energizing current values are extremely small. Allows for more compact size peripheral electrical equipment. Poppet and Diaphragm Construction ③ No sliding parts No valve sticking, for reliable operations. ④ Extremely few cases of vacuum leakage Good vacuum response enables excellent pick-up by a vacuum pad and compact vacuum pump to install. ⑤ Dust-resistant Can be used by installing just an ordinary air filter, even in dusty locations....
Open the catalog to page 2Half-wave Rectification Solenoid Ingenious self-developed solenoid A silicon diode is installed on the end of the Current Starting current solenoid for half-wave rectification of the alternating current. The solenoid, therefore, possesses midway characteristics between the Starting current Energizing current Energizing current AC solenoid and DC solenoid. In addition, since the armature is designed to move as short a distance as possible, the starting current (inrush Time Current wave form in an abnormal condition. Burn out will occur. Armature Solenoid identical and low current. As a...

Open the catalog to page 41. When mounting a valve inside a control panel or when an operation requires long energizing periods, provide heat radiation measures to ensure that the ambient temperature always remains within the temperature range specifications. For long term continuous energizing, consult us. 2. Always check the Catalog, etc., when carrying out wiring and piping of products to ensure that the connections are correctly done. Wrong wiring or piping could result in abnormal operation to the actuator, etc. 3. The solenoid valve’s silicon diode could be damaged by surge voltage when a large induction load...
