Wafer check valve is also called reverse flow valve, check valve, back pressure valve and one-way valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve.

Advantage:

1.The structural length is short, and its structural length is only 1/4~1/8 of the traditional flange check valve.

2.Small size and light weight, its weight is only 1/4~1/20 of the traditional flange check valve.

3.The valve disc closes quickly and the water hammer pressure is small.

4.Both horizontal and vertical pipes can be used for easy installation.

5.The valve disc travel is short and the closing impact force is small.
