**Product Specifications**
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 prevent degradation from prolonged exposure to sunlight. Each valve undergoes a pressure test before shipping at 15 kg/cm² for quality assurance.
Here is an overview of the internal working mechanism:
1. These water treatment diaphragm valves are ideal for use in sand filters, replacing two sets of electric or pneumatic valves, offering easy control and operation.
2. Made from PA6 (Nylon), they can withstand a maximum working pressure of 1.0 MPa.
3. Equipped with a clamp connection, installation and removal are simple and quick.
4. Resistant to rust and corrosion, they are suitable for use in weak acid environments.
5. Excellent aging resistance allows for safe outdoor use.
6. Quick switching and stable operation ensure reliable performance.
7. Easy to replace parts, which helps reduce maintenance costs.
8. The diaphragm is made from advanced rubber material with excellent elasticity, reinforced with imported high-strength net cloth for superior rebound performance.
9. Features bilateral dovetail waterproof rubber seals to prevent leakage during operation.
10. A hold hoop on top enhances safety and simplifies internal part replacement.
11. Finished with professional nylon paint, ensuring a durable and attractive appearance.
