Non-Return Valve

Introduction:

The function of the non-return valve is to ensure the directional flow of the medium in the pipeline without backflow.

It is used in pipelines of various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries, and the applicable medium is water, oil, steam, acid medium, etc.

It is a valve that controls the one-way flow of the medium in the pipeline to prevent the backflow of the medium in the pipeline.

Product installation:

Do not make the non-return valve bear weight in the pipeline. The large non-return valve should be supported independently so that it will not be affected by the pressure generated by the pipeline system.

When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow marked on the valve body.

The lift-type vertical flap non-return valve should be installed on the vertical pipeline.

The lift-type horizontal flap non-return valve should be installed on the horizontal pipeline.
