**Product Description**
Water treatment diaphragm valves are lightweight and rust-free compared to traditional iron valves. They are designed with anti-aging properties to prevent degradation from sunlight exposure. Each valve undergoes pressure testing before shipment at 15 kg/cm².
Key features include:
1. Ideal for use in sand filters, replacing two sets of electric or pneumatic valves for easier control.
2. Made from PA6 (Nylon), with a maximum working pressure of 1.0 MPa.
3. Uses clamp connection for easy installation and removal.
4. Resistant to rust and corrosion, suitable for weak acid environments.
5. Excellent aging resistance, suitable for outdoor use.
6. Quick switching and stable operation.
7. Easy to replace parts, reducing maintenance costs.
8. The diaphragm is made from advanced rubber with high elasticity, reinforced with imported high-strength fabric for better rebound.
9. Features a bilateral dovetail waterproof rubber seal ring to prevent water leakage.
10. Includes a hold hoop on top for safer handling and easier internal part replacement.
11. Finished with professional nylon paint for an attractive appearance.
