**Product Specifications**
**Product Description** Our water treatment diaphragm valves are designed for durability and efficiency in various industrial applications. Compared to traditional iron-made valves, these models are lighter, corrosion-resistant, and feature an anti-aging coating that protects against UV damage. Each unit undergoes a pressure test at 15 kg before shipment to ensure quality. Key Features: 1. Ideal for use in sand filters, replacing two sets of electric or pneumatic valves. 2. Made from PA6 (Nylon), with a maximum working pressure of 1.0 MPa. 3. Clamp connection design for easy installation and maintenance. 4. Resistant to rust and weak acids, suitable for long-term outdoor use. 5. Excellent aging resistance and high operational stability. 6. Quick switching and easy replacement of parts, reducing maintenance costs. 7. The diaphragm is made from advanced rubber with high elasticity and reinforced with imported high-strength fabric. 8. Equipped with a bilateral dovetail waterproof rubber seal ring to prevent leakage. 9. Includes a top hold hoop for enhanced safety and ease of internal part replacement. 10. Finished with professional nylon paint for a durable and attractive appearance. **Frequently Asked Questions (FAQ)** **Shipping Methods:** 1. **Express Shipping:** DHL, TNT, UPS, FEDEX, EMS – ideal for small or urgent orders. 2. **Sea Freight:** Suitable for bulk orders. 3. **Air Freight:** Fast delivery for time-sensitive shipments. **Delivery Time:** - Sample orders: 5–7 days after payment. - Regular orders: 7–15 days after payment (excluding weekends). **Returns & Warranty:** - If no quality issues are found, returns are not accepted.
