Dual Plate Wafer Check Valve – YONCO High-Performance Non-Return Valve
The YONCO Dual Plate Wafer Check Valve is an advanced, multi-purpose non-return valve that is significantly stronger, lighter in weight, and smaller in size compared to conventional swing check valves. Engineered with a spring-loaded dual-plate design, it ensures an incredibly fast response to flow reversal, effectively eliminating water hammer and ensuring silent operation. It is the ideal space-saving solution for water supply, oil, gas, and chemical processing pipelines.
Core Features & Advantages
- Compact Wafer Design: The short face-to-face dimension allows for easy installation between flanges in tight spaces, reducing piping support requirements and installation costs.
- Water Hammer Prevention: The dual-plate structure is spring-assisted, allowing the valve to close almost instantaneously as the flow velocity decreases, preventing slamming and pressure surges.
- Zero Leakage Performance: Precision-machined seats (available in EPDM, NBR, or Viton for soft sealing; Stellite for hard sealing) ensure a bubble-tight shut-off.
- Low Pressure Drop: The streamlined internal flow path and independent plate action minimize turbulence and energy loss.
- Versatile Mounting: Can be installed in both horizontal and vertical upward flow orientations.
