A 3/4 inch AC220V pneumatic normally closed electric solenoid valve is an electromechanical device used to control the flow of a fluid or gas in a system. It is designed to be used with a 220 volt AC power supply. "Normally closed" means that in its rest state (when not electrically powered), the valve maintains its orifice closed, thereby blocking flow through it. Once electrical voltage is applied to its coil, the valve activates, opening and allowing flow to pass through. Material: Brass Type : Normally closed type (N/C) Action Move : Direct Action Working environment: Air, water, oil Fluid temperature: -5~80°C Working pressure: 0~1.0MPA Voltage: AC220V
