A. 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. It stays close when the coil is de-energized and opens when energized. It has two holes in the bottom and can be mounted in any position. It is 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. B. 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 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, suitable for electrically driven pneumatic power control. C.
