Electric 12V Flush Diaphragm Valve – 2 Inch
The water treatment diaphragm valves are lightweight and rust-free compared to traditional iron valves. They are treated with anti-aging properties to prevent degradation from sunlight exposure. Each valve undergoes a pressure test before shipping (up to 15kg).
Here is the working mechanism of its internal structure:


1. These water treatment diaphragm valves can be used in sand filters, replacing two sets of electric or pneumatic valves, making control easier.
2. Made from PA6 (Nylon) material, with a maximum operating pressure of 1.0MPa.
3. Features a clamp connection for easy installation and removal.
4. Resists corrosion and can be used in weak acid environments.
5. Excellent aging resistance, suitable for outdoor use.
6. Operates quickly and provides stable performance.
7. Easy to replace parts, which reduces maintenance costs.
8. The diaphragm is made of advanced rubber with high elasticity, reinforced with imported high-strength fabric for better rebound.
9. Equipped with bilateral dovetail waterproof rubber seals to prevent leakage during operation.
10. Features a top hold hoop for added safety and ease of internal part replacement.
11. The exterior is finished with professional nylon paint for an attractive appearance.
