Valve Failures and Causes | Problems in Industrial Valves

Valves, which control fluid flow in industrial facilities, are critical equipment for the safe and efficient operation of systems. However, valve failures can occur over time, leading to production losses, increased costs, and safety risks.

So why do valve failures occur and how can they be prevented?

What is a valve malfunction?

Valve failure occurs when a valve is unable to perform its fluid control function or experiences a loss of performance. These failures can manifest as loss of sealing, difficulty opening and closing, inability to maintain pressure, or complete failure to function.

Main Causes of Valve Failure

1. Wear and Tear

Valves wear out over time due to constant opening and closing motion and operation under high pressure. Loss of sealing occurs especially as a result of friction between moving parts.

2. Corrosion

In environments such as chemical fluids, water, and steam, corrosion is one of the most common causes of valve failure . Rusting weakens the valve body and shortens its lifespan.

3. Incorrect Valve Selection

Selecting a valve that is not suitable for the pressure, temperature, or fluid type will quickly lead to performance loss and failures.

4. Lack of Maintenance

Leaks, loosening, and seal problems are common in valves that do not receive regular maintenance. When maintenance is neglected, small problems can escalate into costly malfunctions.

5. High Pressure and Temperature

Exposing valves to pressures and temperatures exceeding their operating limits can cause deformation and body cracks.

6. Assembly Errors

Incorrect installation, connection errors, or the use of unsuitable seals are also common causes of valve failure .

Symptoms of Valve Failure

• A sound (vibration or humming) coming from the valve.

• Difficulty opening and closing

• Leakage or dripping

• Pressure imbalance

• poor performance

When these symptoms are observed, prompt action is necessary to prevent the malfunction from escalating.

Ways to Prevent Valve Failures

• Regular maintenance and periodic testing.

• Correct valve selection (suitable for pressure, temperature, and fluid)

• Choosing corrosion-resistant materials.

• Professional installation and use of certified equipment.

• Using original or equivalent quality parts when replacing spare parts.

These methods minimize the risk of failure and ensure production continuity in facilities.

Conclusion

Valve failure is a serious problem in industrial facilities, negatively impacting production safety and efficiency. Wear, corrosion, incorrect valve selection, and lack of maintenance are among the most common causes. Regular inspections and certified maintenance services can prevent these failures.

Remember, timely action prevents huge costs.
