**Product Description** Water treatment diaphragm valves are lightweight and corrosion-resistant compared to traditional iron valves. They are equipped with anti-aging properties to prevent degradation from UV exposure. Each valve undergoes pressure testing before shipping at 15 kg/cm². Here is an overview of the internal working mechanism: 1. These valves can be used in sand filters, replacing two sets of electric or pneumatic valves, making control more convenient. 2. Made from PA6 (Nylon), they can handle a maximum operating pressure of 1.0 MPa. 3. Feature 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. Quick switching and stable operation. 7. Easy to replace parts, resulting in low maintenance costs. 8. The diaphragm is made from advanced rubber with high elasticity, reinforced with imported high-strength net cloth for better rebound performance. 9. Equipped with bilateral dovetail waterproof rubber seals to prevent leakage during operation. 10. Features a hold hoop on top for added safety and easier internal part replacement. 11. Finished with professional nylon paint for a durable and attractive appearance. **FAQ** **Shipping Methods:** 1. Express delivery (DHL, TNT, UPS, FEDEX, EMS) – ideal for small or urgent orders. 2.
