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-crafted design
Our water treatment diaphragm valves are lightweight and resistant to rust, making them a superior alternative to iron-based models. They are also treated with anti-aging agents to prevent degradation from sunlight exposure. Each unit undergoes pressure testing before shipment at 15 kg/cm² for quality assurance.
Here’s an overview of the internal working mechanism:
1. These water treatment diaphragm valves can be used in sand filters, replacing two sets of electric or pneumatic valves, offering easy control and operation;
2. Made from PA6 (Nylon) material, capable of handling a maximum operating pressure of 1.0 MPa;
3. Feature a clamp connection for simple installation and removal;
4. Resistant to rust and corrosion, suitable for use in weak acid environments;
5. Excellent aging resistance, ideal for outdoor applications;
6. Fast switching with stable operational performance;
7. Easy to replace parts, ensuring low maintenance costs;
