Control valves: what they are, how they work, and their ideal maintenance Safety valves 10/10/2025
Control valves are essential components in industrial systems that manage the flow of fluids—whether liquids, gases, or steam— within a facility. Their main function is to regulate the pressure, flow, or temperature of the fluid, thus ensuring efficient, safe, and stable operation of the entire production process.
In sectors such as petrochemicals, power generation, food, and water treatment, these valves are key to maintaining operating parameters within established limits. Hence, the installation of control valves in Tarragona and their proper maintenance are essential to prevent unexpected shutdowns or loss of performance.
How do control valves work?
The operating principle is based on modifying the opening of its shutter, which allows the fluid flow to be adjusted based on the signal it receives from the control system. This signal can be pneumatic, electric, or hydraulic. Thanks to this mechanism, the valve responds in real time to the needs of the process, maintaining optimal pressure and flow.
There are different types of control valves depending on the type of fluid, the working pressure, and the degree of precision required. The most common are globe, butterfly, ball, and diaphragm valves, each with specific characteristics that make them more suitable for certain industrial applications.
Maintenance and Service Life of Control Valves
Control valve maintenance is crucial to prolonging their useful life and avoiding costly breakdowns. Over time, wear due to friction, corrosion, or sediment buildup can affect the system's performance. Therefore, it is recommended to perform periodic inspections, internal cleaning, calibration, and, if necessary, component replacement.
Control valve repair should be performed by specialized technicians who can ensure the proper restoration of original operating conditions. In general, a well-maintained control valve can have a lifespan of between 10 and 20 years, depending on the intensity of use, the type of fluid, and environmental conditions.
