Lug Type Check Valve is used in pipeline system, its main function is to prevent medium backflow, pump and its drive motor reverse, as well as the discharge of medium in the container. According to the different materials, the check valve can be applied to various medium pipelines. When the check valve is installed on the pipeline, it becomes one of the fluid components of the whole pipeline.
Series - 150 To 2500
The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located. Conversely, the closing characteristics of the valve disc have an effect on the flow state of the fluid.
