10 Inch 1.6MPa Flange EPDM Rubber Duckbill Check Valve OEM Support

Performance characteristics of duckbill valves

1. Simple structure: The duckbill valve is composed of valve body, valve disc, valve stem, etc., which is easy to manufacture and maintain.

2. Easy installation: The installation method of duckbill valve is flexible and diverse, can be repaired, and is suitable for different installation environments.

3. Strong corrosion resistance: The body and disc materials of the duckbill valve are mostly made of stainless steel, cast steel and other corrosion-resistant materials, which can be used for a long time in corrosive media.

4. Good sealing performance: Metal-to-metal sealing is adopted between the disc and the seat of the duckbill valve, which effectively prevents the leakage of medium.

5. Self-cleaning function: The internal design of the duckbill valve helps to clean automatically and reduce sediment and sludge deposition.

6. Anti-freeze performance: The duckbill valve has good flexibility and elastic deformation, and is suitable for low temperature environment.

Installation method

The installation method of duckbill valve mainly includes the following steps:

1. Choose the right size and material: Choose the right duckbill valve size and material according to the application needs, considering factors such as the type of fluid, pressure and temperature.

2. Clean and prepare the pipes: Make sure the pipes are clean and free of impurities or contaminants before installation, you can use a soft brush or cloth to remove the dirt, and if necessary, use lubricant to help the valve slide into position.

3. Install the valve correctly: Slide the valve to the end of the pipe, make sure the "duckbill" is facing the flow direction, and gently slide in to avoid forcing or damaging the valve.

4. Sealing treatment: Add a clamp to fix the valve as needed to ensure that the clamp is tight but not to damage the valve or pipeline.

5. Test for leaks: Test for leaks after installation, make sure it is working properly by running water or air through the pipes and checking for signs of backflow or leakage.
