Swing Check Valve: Causes of Failure and How to Diagnose and Resolve Them

Swing check valves are an important part of many industrial and commercial piping systems. They are used to prevent backflow and protect against system contamination. However, swing check valves can fail for a variety of reasons. In this article, we will look at the most common causes of swing check valve failure and how to diagnose and resolve them. We will also discuss the benefits of regular swing check valve inspections.

 

A swing check valve is a mechanical device that allows fluid to flow in only one direction, while preventing backflow in the opposite direction. It consists of a movable disk or “clapper” that is attached to a hinge, and a seat upon which the clapper rests when closed. 

Causes of Swing Check Valve Failure

There are a few common causes of swing check valve failure. The first is improper installation. If the valves are not installed correctly, they can become damaged and fail to function properly.

Another common cause of failure is corrosion. Swing check valves are exposed to a lot of water and other corrosive materials, which can damage the valves and cause them to fail.

Finally, swing check valves can also fail due to debris or other objects getting lodged in the valve. This can cause the valve to become stuck open or closed, which can lead to serious problems.

If you think that your swing check valve may be failing, it is important to contact a professional for help. A qualified technician will be able to diagnose the issue and provide recommendations on how to proceed. In most cases, the problem can be fixed without too much difficulty.

How to Diagnose and Resolve Swing Check Valve Failure

If a swing check valve is failing to function properly, there are a few things that can be done to diagnose and resolve the issue. First, it is important to check the valve for proper installation. If the valve is not installed correctly, it will not be able to seal properly and will allow fluid to leak through. 

Additionally, the valve may be installed backwards, which will cause it to seal improperly. If the valve is installed correctly, the next step is to check for debris or foreign objects that may be blocking the valve from sealing properly. Finally, if the valve is still not functioning properly, it may need to be replaced.

Swing check valves are an important part of many different types of systems, and they should be properly maintained in order to ensure that they continue to function properly. By taking the time to diagnose and resolve any issues that may arise, you can help to keep your system running smoothly.

Final thoughts

While the causes of swing check valve failure can vary, there are a few key things you can do to diagnose and resolve them. By being aware of these common issues, you can help keep your valves functioning properly and avoid costly damage or replacements.
