Dual Plate Wafer Type Check Valve

  • 1. Small in size, light in weight, compact in structure,easy in maintenance.
  • 2. Two torsion springs are used excreting on each of the pair valve plates,which close the plates quickly
  •    And automatically.
  • 3. The quick-close action prevents the medium from flowing back and eliminates water hammer effect.
  • 4. Short body structure length and good rigidity.
  • 5. This valve is tightly sealed, without leakage under the pressure water test.
  • 6. Safe and reliable in operation,high interference-resistance.
