**Product Specifications**
**Product Description**
The water treatment diaphragm valves are designed to be lightweight and corrosion-resistant compared to traditional iron valves. They feature an anti-aging additive that protects against UV degradation, ensuring long-term durability even when used outdoors. Each valve undergoes a pressure test before shipping at 15 kg/cm². Below is an overview of the internal working process: 1. These valves are ideal for use in sand filters, replacing two sets of electric or pneumatic valves, offering simple and efficient control. 2. Made from PA6 (Nylon), with a maximum working pressure of 1.0 MPa. 3. Uses a clamp connection for easy installation and removal. 4. Non-rusting and highly resistant to corrosion, suitable for weak acid environments. 5. Excellent aging resistance, making them suitable for outdoor applications. 6. Fast switching and stable operation. 7. Easy to replace parts, resulting in low maintenance costs. 8. The diaphragm is made from advanced rubber material with good elasticity, reinforced with imported high-strength fabric for improved rebound performance. 9. Features a bilateral dovetail waterproof rubber seal ring to prevent leaks during operation. 10. Equipped with a top hold hoop for added safety and ease of internal part replacement. 11. Finished with professional nylon paint for a smooth and attractive appearance. **FAQ** **Shipping Options:** 1. Express shipping (DHL, TNT, UPS, FEDEX, EMS) – ideal for small or urgent orders. 2.
