What is the purpose of a safety valve in pressure systems?

The purpose of a safety valve in pressure systems is specifically to release excess pressure. In many industrial applications, systems can build up excessive pressure due to various factors such as changes in temperature or unexpected system conditions. If this pressure exceeds a predefined limit, the safety valve automatically opens to allow a safe release of pressure, thereby preventing potential equipment failure or explosions. This function is crucial for maintaining the integrity and safety of pressure systems, as it helps to manage pressure fluctuations and protect both the equipment and the personnel working in the vicinity.

In contrast, measuring pressure is the role of a pressure gauge, regulating flow is a function of control valves, and filtering contaminants is managed by filters, highlighting the distinct and vital role safety valves play in pressure management.
