Product Description
Water treatment diaphragm valves are lightweight and rust-resistant compared to iron-made alternatives. They are treated with anti-aging agents to prevent degradation from sunlight exposure. Each valve undergoes pressure testing before shipment at 15 kg/cm². Below 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 them easy to control. 2. Made from PA6 (Nylon) material, they can withstand a maximum working pressure of 1.0 MPa. 3. Featuring a clamp connection, they are easy to install and remove. 4. Resistant to rust and corrosion, they are suitable for use in weak acid environments. 5. Excellent aging resistance allows them to be used outdoors without significant performance loss. 6. Quick switching and stable operation make them ideal for various applications. 7. Easy to replace parts, reducing maintenance costs. 8. The diaphragm is made of advanced rubber with good elasticity, reinforced with imported high-strength fabric for better rebound. 9. Equipped with bilateral dovetail waterproof rubber seals to prevent leaks during operation. 10. A top hold hoop ensures safety and ease of internal part replacement. 11. The exterior is coated with professional nylon paint, offering a neat and durable finish. FAQ **Shipping Options:** 1. By express: DHL, TNT, UPS, FEDEX, EMS, etc., typically for small or urgent orders. 2. By sea: For bulk quantities. 3.
