Top-Quality 2 Way Diaphragm Water Treatment Hydraulic Solenoid Valve
1. Water Treatment Diaphragm Valves
2. Hydraulic or Pneumatic Operation
3. Competitive Manufacturing Price
4. Durable and Well-Refined Design
Our water treatment diaphragm valves are designed for long-lasting performance and reliability. Compared to traditional iron valves, they are lighter and corrosion-resistant. They are also treated with anti-aging properties to prevent degradation from sunlight exposure. Each valve undergoes a pressure test of 15 kg before shipping to ensure quality.
Below is a detailed explanation of the internal working mechanism:
1. These water treatment diaphragm valves can replace two sets of electric or pneumatic valves in sand filters, making them easier to control;
2. Made from PA6 (Nylon), with a maximum operating pressure of 1.0 MPa;
3. Clamp connection design allows for easy installation and removal;
4. Rust-free and resistant to corrosion, suitable for weak acid environments;
5. Excellent aging resistance, ideal for outdoor use;
6. Fast switching and stable operation;
7. Easy to replace parts, low maintenance cost;
8. The diaphragm is made of high-quality rubber with advanced elasticity, reinforced with imported high-strength fabric for better rebound;
9. Features a bilateral waterproof rubber seal ring to prevent leaks;
