Its high efficiency and convenience make it an important part of modern automation control. So, how does the water solenoid valve work? How to choose the right product for your needs? This article will explain it in detail.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-normal-font-size\">1.Basic concept of water solenoid valve<\/h2>\n\n\n\n<p class=\"has-foreground-color has-text-color has-link-color has-normal-font-size wp-elements-2 wp-block-paragraph\">\u200cwater solenoid valve \u200c is an automatic component that uses electromagnetic force to control the flow of fluid, mainly used to control the flow of water or other liquids. The water solenoid valve controls the movement of the valve core through the magnetic field generated by the electromagnet, so as to realize the opening or closing of the valve. When the electromagnet is energized, the magnetic force generated attracts the spool and makes the valve open; When the power supply is disconnected, the magnetic force disappears, the spool returns to its original position, and the valve is closed. <\/p>\n\n\n\n<h2 class=\"wp-block-heading has-normal-font-size\" style=\"padding-bottom:var(--wp--preset--spacing--10)\">2.Working
