**Product Description** Water treatment diaphragm valves are lightweight and corrosion-resistant compared to traditional iron valves. They are treated with anti-aging materials to prevent degradation from sunlight exposure. Every unit is pressure tested before shipping at 15 kg/cm². Here’s how the internal structure works: 1. These valves are ideal for use in sand filters, replacing two sets of electric or pneumatic valves, offering easier control. 2. Made from PA6 (Nylon), with a maximum working pressure of 1.0 MPa. 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, making them suitable for outdoor use. 6. Fast switching and stable operation. 7. Easy to replace parts, resulting in low maintenance costs. 8. The diaphragm is made of advanced rubber with good elasticity, reinforced with imported high-strength fabric for excellent rebound performance. 9. Equipped with bilateral dovetail waterproof rubber seals to prevent water leakage during operation. 10. Includes a top hold hoop for added safety and ease of internal part replacement. 11. Finished with professional nylon paint for an attractive appearance. **FAQ** **Shipping Options:** 1. Express shipping (DHL, TNT, UPS, FEDEX, EMS) – ideal for small or urgent orders. 2.
