It is common for cavitation to occur in various devices, so we must correctly monitor our equipment and pipes so that our system does not suffer any unexpected production stoppage.
Cavitation occurs when the bubbles of a fluid undergo changes due to different factors. Only liquid fluids are the only ones that suffer from this phenomenon. The main factors are the pressure and speed that suddenly form bubbles and achieve an explosion that changes the environment; They produce various effects on the equipment and pipes such as noise, knocking, vibrations and erosion to such an extent that they reduce the flow.

In control valves they usually have these same factors, however, in all types of valves and pumps these situations can occur. Therefore, the equipment must be attended to and previously carry out a specific analysis to reduce the risks.
We must take into account the following:
- Definition of the TRIM: the internals of the valves are very important due to the contact they have with the fluid. The correct definition of this depends to a large extent on the useful life of our valves and unexpected stoppages in the plant.
- Design of the Pumping System: it is fundamental to be able to deliver to our process the necessary amount of fluid for it to function correctly. By having the details of the process we can get closer to reducing risks.
- Installation of adequate suction lines.
- Filtration removal from the suction line.
- Maintaining an adequate temperature of the fluid: this is essential to avoid having sudden changes and collapsing our process.
Control valves are a fundamental element to regulate in the following applications: steam, chemical industry, water treatment, gas.
Come with us to receive advice on these teams and other elements that make up your process.
