Customized Wafer Check Valve Manufacturers and Suppliers with the Price List
1.Introduction of Wafer Check Valve
Wafer check valve is also known as counter flow valve, check valve, back pressure valve, one-way valve. This kind of valve is automatically opened and closed by the force generated by the flow of medium itself in the pipeline, which belongs to an automatic valve.
Wafer 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.

4.Application of Wafer Check Valve
Wafer check valves can also be used to supply lines to auxiliary systems where the pressure may rise above the main system pressure. According to the different materials, the waffer check valve can be applied to various medium pipelines. When the wafer check valve is installed on the pipeline, it becomes one of the fluid components of the whole pipeline. The opening and closing process of the valve disc is affected by the transient flow state of the system in which it is located; On the other hand, the closing characteristics of the disc have an effect on the flow state of the fluid.
Small size, light weight, compact structure, easy maintenance.
The valve plate adopts dual type, which can close automatically under the elastic moment of spring.
Due to the quick closing effect, it can prevent the medium from backflow and eliminate water hammer.
The valve body has the advantages of small length, good rigidity, safety and reliability.
Complete sealing and zero leakage in hydrostatic test.
Wafer check valve is easy to install, and can be used for horizontal and vertical installation.
