Product Description
Water treatment diaphragm valves are lightweight and corrosion-resistant compared to traditional iron-made valves. They are designed with anti-aging properties to ensure durability even under prolonged sunlight exposure. Every valve undergoes a pressure test before shipping at 15 kg/cm². The internal structure is efficient and reliable for various applications. Here's how the water treatment diaphragm valve works: 1. It can be used in sand filters, replacing two sets of electric or pneumatic valves, making it easy to control. 2. Made from PA6 (Nylon) material, with a maximum working pressure of 1.0 MPa. 3. Uses clamp connection, which makes installation and removal quick and simple. 4. Resists rust and corrosion, suitable for use in weak acid environments. 5. Offers excellent aging resistance, ideal for outdoor applications. 6. Provides 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 better rebound performance. 9. Features a bilateral dovetail waterproof rubber seal ring to prevent leakage during operation. 10. Equipped with a hold hoop on top, ensuring safety and ease of internal part replacement. 11. The exterior is treated with professional nylon paint for an attractive appearance. FAQ
