Advanced Spring-Loaded Disc Mechanism

Dual plate check valves consist of two semi-circular plates hinged on a central pin. This design ensures rapid closure with spring assistance the moment flow stops, minimizing the risk of **water hammer**, which can cause severe pipeline damage. Its wafer body design provides up to 80% weight reduction compared to conventional flanged swing check valves, offering significant ease of installation. Combining a ductile iron body with stainless steel plates, these valves are essential for HVAC systems, water networks, and fire protection lines.

Structural Features

  • Body: Cast Iron (GG25) or Ductile Iron (GGG40.3).
  • Plates: AISI 304 / 316 Stainless Steel.
  • Seals: EPDM, NBR, or Viton for high temperatures.

Performance Benefits

  • Silent Closure: Dampens backflow impact via spring tension.
  • Low Pressure Drop: High flow capacity with aerodynamic plates.
  • Flexible Installation: Suitable for horizontal and vertical (upward) flow.
