In the daily life of industrial facilities, safety valves play a fundamental role in ensuring the protection of equipment, processes, and people. However, over time and with continued use, certain failures often appear that, if not detected and resolved in a timely manner, can jeopardize the safety of the entire plant.

As specialists in safety valve maintenance and repair, we want to help you identify the most common problems and explain how we solve them so that your equipment operates correctly, with maximum reliability, and in compliance with current regulations.

Most common failures in safety valves

Valve leaks

One of the most common failures is fluid leaks through the seat or body joint. These leaks can be due to wear of internal components, scale, misalignment, or defects in the seal.

How do we fix it?

We perform thorough cleaning, seat grinding, and replacement of worn or defective parts. We then perform leak tests to ensure proper sealing.

Opening Overpressure

When the valve does not open to the calibrated pressure, it may indicate a spring miscalibration, internal deformations, or a buildup of debris that prevents proper operation.

How do we solve it?

We perform precise recalibration using approved equipment and, if necessary, replace the spring elements or adjust the internal components to return the valve to its correct opening parameters.

Blockage or partial opening

If the valve remains partially open or blocked, it is usually due to dirt, internal corrosion, or mechanical defects.

How do we fix it?

We perform mechanical and chemical cleaning of the internal ducts, remove debris, and, if necessary, replace damaged parts. Additionally, we apply anti-corrosion treatments to extend the equipment's lifespan.

Unusual vibrations or noises

Unusual vibrations or noises are usually related to flow instability, calibration errors, or component wear.

How do we fix it?

We analyze the valve's dynamic behavior, review the system configuration, and correct any mechanical or adjustment anomalies that may cause instability.

Our diagnostic and repair process

In each intervention, we follow a rigorous protocol to guarantee reliable and long-lasting results:

• Complete visual and functional inspection
• Disassembly, cleaning, and technical analysis
• Repair or replacement of defective parts
• Recalibration according to regulations
• Functional testing and final certification

In addition, we offer an urgent industrial valve repair service to minimize downtime and ensure continued safety in your plant.
