Product Overview
The Silent Check Valve is engineered to provide quiet and efficient backflow prevention, especially in pump discharge and high-flow systems.
Its spring-assisted axial flow design ensures rapid disc closure, effectively minimizing water hammer and eliminating noise generated during valve operation.
It is widely used in water supply systems, HVAC pipelines, booster pump stations, fire protection systems, and industrial fluid networks.
