The 2-way 2 position normally closed air gas directional control solenoid is to control On/Off of air, inert gas, liquid, and vacuum. This solenoid has 1/8" inch BSP thread. stays close when the coil is de-energized- and it opens when energized. Has two holes in the bottom and can be mounted in any position. It's suitable for liquid, water, oil, high-end water heaters, intelligent drinking fountains, water heaters, straight drinking machines, water purification machines, steam machines, energy-saving air-conditioning, water treatment, cooling equipment and water industry and other fields. Features: - Robust aluminum alloy shell, anti-corrosion, durable, gasket of solenoid is equipped with heat resistance grade B, sealing is made of butylcyanide, which ensures great-leakage proof effect.- Direct operated type normally closed 2-way solenoid valve, quick direction changing and high sensitivity.- DC 12V 1/8" quick connect solenoid valve. Light and compact structure.- Keep constant current steady flow as well as preventing the dry burning and monitoring the flow.- Normally Closed. Open when current through, closed when no current through.- Designed to control automatically the liquid and gas, perfect for electrically driven pneumatic power control.
