What Is the Influence and Harm of Scale on Valves?

For any valve, dirt in it will affect its normal service life, which will not only cause leakage of the valve, but also affect its work, so how to remove the scale is a problem that everyone is concerned about now.
 
The control valve is most likely to cause fouling, which has a great relationship with design and filling materials. First, there will be deviation from parameter variables in the process of manufacturing, so these dead zones must be overcome in the controller. There are many factors affecting the dead zone, such as friction, amplifier, etc., which can form the dead zone. Various control valves have different sensitivity to friction, while rotary valves are very sensitive to friction, so we should pay attention to the performance of various valves when using them. For some valves with good sealing performance, the design of the valve itself is not perfect, so many dead zones will occur, which will have a great influence on the deviation.
 
The wear between valves is also the main reason, which is obvious in the lubricating layer. According to the test, the lubrication rotary valve will wear if it is used for several hundred times, so keep your eyes open when choosing the valve.
