The Dual Plate Wafer Type Check Valve is a high-efficiency backflow prevention solution engineered for modern industrial piping. Featuring a compact wafer-style body and two spring-loaded discs hinged at the center, this valve ensures rapid closure and minimal pressure loss. By significantly reducing the closing stroke, it effectively mitigates the water hammer phenomenon, protecting your pipeline infrastructure from mechanical stress and potential failure.
Designed for versatility, these valves are ideal for municipal water supply, industrial drainage, and high-rise building networks. Whether installed in horizontal or vertical orientations, the dual plate design offers a space-saving alternative to traditional swing check valves. Manufactured by Ningjin Thriveon using premium stainless steel and carbon steel, our valves meet rigorous international standards for durability and corrosion resistance in demanding global environments.

| Feature | Dual Plate Wafer | Swing Check Valve |
|---|---|---|
| Space Requirement | Compact / Minimal | Large / Heavy |
| Closing Speed | Ultra-Fast (Spring) | Slower (Gravity/Flow) |
| Water Hammer Risk | Very Low | Moderate to High |
| Pressure Loss | Low / Efficient | Higher resistance |
| Installation Cost | Low (Wafer fit) | Higher (Support needed) |
The dual plate wafer check valve is more compact, provides faster closure to prevent water hammer, and generally causes less pressure drop, making it ideal for high-pressure and space-constrained systems.
Yes, due to the spring-loaded mechanism, these valves can be installed in both horizontal and vertical orientations without affecting their closing efficiency.
For seawater or industrial chemicals, we recommend our premium stainless steel valves, which offer superior corrosion resistance and long-term durability.
Double check valves provide redundant protection using two independent valves in one body, ensuring that if one fails, backflow of contaminated media is still prevented.
Selection should be based on the pipe diameter (ranging from 2" to 48") and the system's pressure rating. Our engineering team can provide technical guidance based on your specific flow requirements.
Yes, especially in vibration-prone systems. The dual plate structure offers greater stability and longevity compared to single-disc swing valves, reducing the frequency of replacements.
