2 Way Diaphragm Water Flow Hydraulic Nylon Water Control Valve
1. Water treatment diaphragm valves
2. Hydraulic or Pneumatic
3. Competitive manufacturing price
4. Durable and high-quality construction
Water treatment diaphragm valves are lightweight and resistant to rust, making them a superior alternative to traditional iron-based valves. These valves are specially treated with anti-aging properties to ensure long-lasting performance even when exposed to sunlight. Each valve undergoes rigorous pressure testing before shipment, with a test pressure of 15kg to guarantee reliability.
Here is an overview of the internal working mechanism:


1. Water treatment diaphragm valves can be used in sand filters, replacing two sets of electric or pneumatic valves, offering easier control and operation;
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. Resistant to rust and corrosion, suitable for use in weak acid environments;
5. Excellent aging resistance, ideal for outdoor applications;
6. Fast switching and stable operation;
7. Easy to replace parts, resulting in lower maintenance costs;
8. The diaphragm is made from advanced rubber material with excellent elasticity, reinforced with imported high-strength fabric for better rebound performance;
9. Equipped with bilateral dovetail waterproof rubber seals to prevent water leakage during operation;
10. Features a top hold hoop for enhanced safety and convenience when replacing internal components;
11. Finished with professional nylon paint treatment for an attractive appearance.
