Automatic Water Filling 24V Hydraulic Solenoid Motorized Valve
1. Water Treatment Diaphragm Valves
2. Hydraulic or Pneumatic Operation
3. Competitive Manufacturing Price
4. Durable and Well-Designed
Water treatment diaphragm valves are lightweight and rust-resistant compared to traditional iron valves. They are equipped with anti-aging properties to prevent degradation from sunlight exposure. Each valve undergoes a pressure test before shipping at 15kg.
Below is an overview of the internal working mechanism:


1. These water treatment diaphragm valves can be used in sand filters, replacing two sets of electric or pneumatic valves, making it easier to control;
2. Made from PA6 (Nylon), with a maximum working pressure of 1.0MPa;
3. Features a clamp connection for easy installation and removal;
4. Resistant to rust and corrosion, suitable for weak acid environments;
5. Excellent aging resistance, ideal for outdoor use;
6. Fast switching and stable operation;
7. Easy to replace parts, low maintenance costs;
8. The diaphragm is made of advanced rubber with good elasticity, reinforced with imported high-strength fabric for better rebound performance;
9. Equipped with bilateral waterproof rubber seals to prevent leakage during operation;
10. Includes a hold hoop on top for safer operation and easier internal part replacement;
11. Finished with professional nylon paint for a smooth and attractive appearance.
