Product Advantage
Features:
Operation: The single disc swings open automatically under forward flow pressure and closes via gravity or a spring, ensuring quick response to prevent backflow. This minimizes water hammer compared to dual-plate designs.
Sealing: Often equipped with soft seals (e.g., EPDM, NBR, or Viton) for tight shut-off, though metal-seated options are available for higher temperatures or abrasive media.
Installation: Wafer design allows easy installation in horizontal or vertical (upward flow) pipelines, with minimal space requirements.
Applications:
Widely used in:Temperature Range: Typically -29°C to 180°C , depending on materials.
-Oil and gas pipelines.
-HVAC systems.
-Chemical processing.
-Sewage and drainage systems.
Advantages:
Compact and Lightweight: Wafer design reduces installation space and weight compared to flanged swing check valves.
Low Pressure Drop: Straight-through flow path minimizes resistance.
Quick Closing: Single disc design ensures fast response to flow reversal, reducing backflow and water hammer.
Corrosion Resistance: Stainless steel body enhances durability in corrosive environments like seawater or chemical systems.
Limitations:
Limited Flow Capacity: Single disc may restrict flow compared to dual-plate or swing check valves in larger sizes.
Potential Wear: In high-velocity or turbulent flows, the disc may flutter, leading to wear on the hinge or seat.
Vertical Installation Constraint: Must be installed with upward flow if vertical, to ensure proper disc closure.
