Check valve is an automatic valve, which is mainly used to prevent the reverse flow of medium, reverse rotation of pump and drive motor, and discharge of container medium.

Dual plate wafer check valve is a universal one-way flow valve. It is light in weight, small in volume and easy to install between flanges. The interior of the valve consists of two semicircles, spring and plate.

Lift check valve should be installed on horizontal pipelines, vertical lift check valve and bottom valve are generally installed on vertical pipelines, and the medium flows from bottom to top.

The installation position of swing check valve is not restricted. It is usually installed in horizontal pipelines, but it can also be installed in vertical pipelines or dumping pipelines.

Installation Precautions

1. When placing the pipeline, it should be noted that the passage direction of the wafer check valve is consistent with the flow direction of the fluid;

2. Different check valves should be selected for pipelines installed horizontally or vertically;

3. Use a telescoping tube between the wafer check valve and the butterfly valve. Never connect it directly to other valves;

4. Avoid adding pipe joints and obstructions within the operating radius of the valve plate;

5. Do not install a reducing pipe in front or behind the wafer check valve;

6. When installing the wafer check valve near the elbow, pay attention to leaving enough space.
