Stainless Steel + Red Copper Model: 4V210-08 Common Voltage Range: AC: 15%, DC: 10% Coil Opening: Approx. 8mm/0.3in Working medium: Air Pipe diameter: Inlet, Outlet: G1/4, Exhaust: G1/8 Effective cross-sectional area: 16.0 mm Number of positions: Two of five ways Pressure range: 0.15 ~0.8 mpa Operating temperature: -20~70 Maximum operating frequency: 5 times/second Power consumption: 4.5 VA Waterproof grade: IP65 Application: medical equipment industry, processing industry food, robot industry, chemical application industry, textile industry, automation workshop Package list: 1 x electric solenoid valve Note: 1, the installation of the solenoid valve should pay attention to the boom body which should be compatible with fluid flow. Do not install in areas with direct water dripping or splashing. The solenoid valve must be installed vertically upwards. 2, the solenoid valve should ensure that the power supply voltage is 15%-10% of the normal operating rated voltage fluctuation range. 3. After installing the solenoid valve, there should be no reverse differential pressure in the pipeline. And need to electrify several times, so that the temperature can be officially put into use. 4, the solenoid valve should be carefully cleaned before installation. Through the medium should be free of impurities. The filter is installed in front of the valve. 5, when the breakdown or cleaning of the solenoid valve, in order to ensure that the system continues to work, should be installed a bypass device.6, please note that the new type and the old type of this product will be sent to the random, and make sure you don"t mind before ordering.
