2W Series（Direct-acting and Normally Closed）Fluid Control Valve (2/2 Way)
2W Series（Direct-acting and Normally Closed）Fluid Control Valve (2/2 Way) is suitable for water or liquid as working medium. It can automatically control or remotely control the opening and closing of water, oil, liquid and other working medium pipelines. Because the valve is sealed by rubber, the cleanliness of the working medium is greatly reduced. It has the characteristics of quick opening and closing, high reliability.

Application
1. Household Appliances
Ideal for automatic control systems in washing machines, dishwashers, water heaters, and drinking fountains, enabling precise on/off switching of water flow to enhance operational automation and energy efficiency.
2. Water Treatment & Distribution
Widely adopted in water purifiers, RO systems, water dispensers, and municipal water supply pipelines, providing reliable flow regulation for water filtration, disinfection, and accurate water allocation.
3. Industrial Fluid Handling
Applied in low-pressure industrial equipment such as cooling systems, lubrication lines, and liquid transfer devices, where its corrosion-resistant brass body ensures stable performance in contact with pure water, tap water, and other non-corrosive liquids.
4. Agricultural Irrigation
Integrated into drip irrigation, sprinkler irrigation, and greenhouse watering systems to realize timed and quantitative water supply, helping optimize irrigation efficiency and conserve water resources.
5. Commercial & Catering Equipment
Used in coffee machines, ice makers, beverage dispensers, and commercial dishwashers, supporting fast and accurate water flow control to meet the high-frequency operation needs of commercial scenarios.
