**Product Description** The water treatment diaphragm valves are lightweight and rust-free compared to traditional iron-made valves. They are designed with anti-aging properties to prevent degradation from sunlight exposure. Each unit undergoes a pressure test before shipping at 15 kg/cm². Here is an overview of the internal working mechanism: 1. These valves are ideal for use in sand filters, replacing two sets of electric or pneumatic valves, making them easy to control. 2. Made from PA6 (Nylon), they can handle a maximum working pressure of 1.0 MPa. 3. Equipped with a clamp connection, installation and removal are simple and efficient. 4. The valves are resistant to rust and corrosion, suitable for weak acid environments. 5. Excellent aging resistance allows for long-term outdoor use. 6. Quick switching and stable operation ensure reliable performance. 7. Easy to replace parts, leading to low maintenance costs. 8. The diaphragm is made from advanced rubber with high elasticity, reinforced with imported high-strength fabric for better rebound performance. 9. Features a bilateral dovetail waterproof rubber seal ring to prevent leakage during operation. 10. Includes a top hold hoop for enhanced safety and convenient internal part replacement. 11. Finished with professional nylon paint for a clean and attractive appearance. **FAQ** **Shipping Methods:** 1.
