Wafer Dual Plate Check Valve H76

The H76 Wafer Dual Plate Check Valve is engineered for efficient, reliable backflow prevention in various industrial systems. Its large open area design minimizes pressure drop, delivering up to 80-90% weight reduction compared to conventional flanged check valves. Equipped with spring-activated dual plates, this valve ensures quick closure, preventing water hammer and enabling smooth, silent operation. With easy installation and maintenance, this check valve is an ideal solution for both new and retrofit applications.

Key Features

  • Reduced Pressure Drop: Large open area for optimized fluid flow, reducing energy costs.
  • Lightweight Design: 80-90% lighter than traditional check valves for easier handling.
  • Silent Operation: Spring-activated discs close smoothly to prevent water hammer.
  • Easy Installation & Replacement: Compatible with a range of piping configurations.
