What are the effects and hazards of limescale on valves

For any valve, the dirt inside will affect the normal service life, not only will cause leakage of the valve, but also affect the work, so how to remove scale is now a concern of everyone.

The most likely to cause fouling is the control valve, which has a lot to do with the design and filling materials. First, there will be deviations from the parameter variables during the process of manufacturing, so the controller must overcome these dead zones. There are many factors affecting the dead zone. For example, friction, amplifier, etc. can form a dead zone. The sensitivity of various control valves is different for friction. The rotary valve is very sensitive to friction, so pay attention to each when using it. The performance of the valve. For some valves with better sealing, the design of the valve itself is not perfect, so there will be a lot of dead zones, which has a very large impact on the deviation.

The wear between the valves is also a very important cause. The lubrication layer is very obvious. According to the test, the lubrication rotary valve will wear out if it uses several hundred cycles, so it is necessary to polish the eyes when selecting the valve.
