What is a frequent cause of serious accidents with valves?

In the context of accidents related to valves, unsuitable materials for operating pressures and temperatures is a significant concern. Valves are critical components in refrigerant systems and other piping configurations, and they must be constructed from materials that can withstand both the pressure and the temperature of the fluids they handle. If the material is not appropriate, it may degrade over time, which can lead to failures. A valve made from an unsuitable material may crack, corrode, or otherwise fail to maintain a secure seal under high pressure, potentially resulting in leaks or even catastrophic failures that can cause injury or property damage.

The risks associated with material choice are accentuated in systems that operate under extreme conditions. For instance, if a valve that is not rated for high pressures is installed in a high-pressure system, it can lead to ruptures. Similarly, materials that are not resistant to the specific chemical properties of the fluid can corrode or react in adverse ways. Ensuring that the valve material is suitable for the intended application is crucial for safe operation and prevents accidents related to structural failures or leaks.

While other factors such as lack of maintenance, improperly sized valves, and inadequate operational training can contribute to accidents, the fundamental integrity of the valve materials directly impacts their ability to perform safely under
