2W water solenoid valve

Product Introduction: Water solenoid valve is a common pipeline switch component in automatic control systems. It is the core control equipment of music fountains and is particularly suitable for water control of running and jumping springs. Adopting a membrane structure, it has the characteristics of rapid opening and closing, stable performance, convenient use, high reliability, and long service life. It is widely used in pipeline devices of various industrial sectors such as petroleum, chemical, metallurgical, food, shipbuilding, medical, environmental protection, etc. to achieve automatic control of gas, water, liquid, oil and other media in the system, realizing energy-saving and program control automation.

Product features: 1. The use of plastic sealed coils can improve the safe use of the product in many environments. 2. The use of a direct acting diaphragm structure for pressure free start-up has expanded its application range. 3. The use of a flat membrane structure ensures reliable opening and closing, and enhances the service life of the product. 4. The use of vacuum epoxy plastic sealed coil leak proof structure ensures the safety of underwater operation.

Working principle: Normally closed: When the coil is energized, the pilot valve core is attracted, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve is opened; When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole is closed, the valve chamber is pressurized by the piston throttle hole and the thrust of the reset spring, and the solenoid valve is closed.

Normally open: When the coil is energized, the pilot hole closes, and the upper chamber of the valve is pressurized by the piston orifice and the thrust of the reset spring, causing the solenoid valve to close. When the coil is powered off, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is depressurized, the piston is pushed by the pressure of the lower chamber medium, and the solenoid valve opens.
