Description: The 2-way normally closed universal solenoid is used to control the on/off of fluid. This industrial solenoid has 1/2\" inch NPSM inlet ports. It remains closed when the coil is de-energized and opens when energized. It is suitable for fluid, water, advanced water heaters, intelligent drinking fountains, water heaters, direct drinking machines, water purification machines, steam machines, energy-saving air conditioning, water treatment, refrigeration equipment, and the water industry and other fields, a widely used tool for daily use. Features: - Robust brass with nickel and surface treatment, leak-proof, anti-corrosion, durable and wear-resistant. - DC 12V 1/2in quick connect solenoid valve. - Maintains constant current stable flow as well as prevents dry burning and monitors flow. - Normally closed. Open when power goes through, closed when no power goes through. - Designed to automatically control the fluid. Suitable for hot or cold water.
