Methods for extending the service life of ceramic control valves. Ceramic control valves are often used in harsh operating conditions, installed on heavy industrial pipelines where the working environment is extremely complex. Once problems arise, it is difficult to identify them due to the valves’ bulky design, which can leave people at a loss. Additionally, such issues are related to system operation, system integrity, control quality, and environmental pollution. Therefore, proper use of ceramic control valves and thorough maintenance to extend their service life are paramount considerations when utilizing these valves. The following are 5 methods to extend the lifespan of ceramic control valves. 1. Cleaning pipes extends their lifespan. Weld slag, rust, hardened lime sludge, wires, cloth strips, etc. in the pipelines can cause blockages or jams at the throttle points and guide sections, leading to the destruction of the valve core. This problem often occurs in newly commissioned systems and during the initial period after maintenance. This is the most common fault. In such cases, it is necessary to disassemble it for cleaning in order to remove debris; if the sealing surface is damaged, it should also be ground ； At the same time, open the plug to flush out the slag and clean the pipeline. Before putting it into operation, open the control valve fully, allow the medium to flow for a while, and then proceed with normal operation. 2. Operating at a higher opening degree extends lifespan; when first using a ceramic control valve, it is advisable to operate it at the maximum opening degree, such as 80%. In this way, the initial erosion and wear caused by impurities in the pipeline occur outside the damaged areas of the valve core. After the impurities in the pipeline are removed, the opening degree of the control valve is adjusted to a value slightly higher than the normal level. As the fluid causes further damage to the valve core, the flow rate increases, and the opening degree is correspondingly reduced. This process of continuous damage leads to gradual closure, allowing the entire valve core to be utilized to its full extent, until the root of the valve core and the sealing surfaces are damaged and the valve can no longer be used. 3. Increasing the diameter to extend lifespan: We use the CV value calculation formula to determine the correct CV, thereby selecting an appropriate valve diameter. At the same flow rate, the smaller the valve diameter, the faster the fluid velocity, and the greater the erosion of the valve core and seals by the medium. It is recommended that users increase the valve diameter appropriately within the range where the opening can be freely adjusted, thereby reducing wear. 4. Relocate the areas of damage to extend lifespan – Move the parts that are most damaged to less critical locations, in order to protect the sealing surfaces and throttling surfaces of the valve core and seat. Generally, in ceramic ball valves, the area most subject to erosion and where the fluid velocity is highest is located below the fluid inlet. For the three-piece structure of current ceramic ball valves, it is possible to reverse the orientation of the ball core; this allows one ball core to be used four times at the inlet, thereby extending the valve’s lifespan by four times. 5. Changing the valve structure to improve its lifespan: Ceramic control valves initially used a two-piece structure; to make the valve’s design more efficient, it was changed to the three-piece structure that is used today. This structure features dual valve seats, which provides double sealing capabilities. At the same time, when choosing ceramic ball valves, it is important to select those with a beveled transition design; such control valves can reduce the impact of the fluid.
