Plastic Wafer Check Valve UPVC CPVC PP PVDF

1. Description of plastic wafer check valve:

The wafer PVC plastic check valve refers to the plastic valve that opens automatically depending on the flow of the medium itself and closes the disc of the wafer check valve to prevent the backflow of the medium. It is also called PVC check valve, UPVC check valve, plastic backflow valve and plastic back pressure valve. The non-return valve belongs to a plastic automatic valve, whose main function is to prevent medium backflow, reverse rotation of pump and drive motor, and discharge of container medium. The PVC check valve can also be used on the pipeline to supply the auxiliary system in which the pressure may rise to more than the system pressure.

2. Application of PVC disc check valve:

Plastic check valve only allows the medium to flow in one direction and prevents the flow in the opposite direction. Generally, the disc plastic valve works automatically. Under the action of fluid pressure flowing in one direction, the disc opens; when the fluid flows in the opposite direction, the valve seat is acted by the fluid pressure and the self weight of the disc, so as to cut off the flow. Plastic check valve is generally suitable for cleaning medium, not suitable for medium containing solid particles and high viscosity.
Wafer check valve is a kind of ultra-thin wafer PVC check valve. It has the advantages of simple structure, beautiful appearance, light weight, convenient installation, etc. It is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors, and is most suitable for places with installation space restrictions. It is mainly suitable for water supply system, petroleum, chemical industry, metallurgy and other industrial sectors, and is most suitable for places with installation space restrictions.
1. The structure is short in length, small in volume and light in weight, which brings great convenience to the installation, handling and storage of valves, and can save a lot of materials and reduce the cost.
2. The valve is of integral structure, simple and compact, with small impact force when the valve is closed, small water hammer pressure, long service life and high reliability.
3. It can be installed horizontally or vertically, with light weight. It is unnecessary to set support for the valve.
4. The flow passage is smooth, the fluid resistance is small, and the valve disc can be fully opened under a small pressure difference.
