Features
- Two semicircular spring-loaded discs mounted on a central vertical pivot
- Wafer-style connection for compact, lightweight structure
- Disc opens from base first, minimising seal wear during opening
- Short closing stroke with spring loading for rapid closure, reducing water hammer
- Gradual closure as flow decreases; faster closure during backflow
- Spring closes top of disc first, protecting disc base and prolonging seal life
- Sealing surface options: wear-resistant weld overlay or rubber lining
- Suitable for horizontal and vertical pipeline installation
- Wide range of compatible media including oxidising agents and cryogenic fluids
Description
A dual plate check valve comprising two semicircular, spring-loaded discs mounted on a central vertical pivot within a wafer-style body. The disc opens from the base first under fluid force, minimising seal wear; spring force ensures gradual closure as flow reduces and rapid closure during backflow to mitigate water hammer. Sealing surfaces may be wear-resistant material welded to the body or rubber-lined.
