What is the primary purpose of hydrostatic relief valves?

The primary purpose of hydrostatic relief valves is to reduce pressure within a system. These valves are designed to open and allow fluid to escape when the pressure reaches a certain threshold, thereby preventing potential overpressure situations that could lead to equipment failure or hazardous conditions.

In contexts where liquids like propane are involved, maintaining safe pressure levels is crucial, especially since increased pressure can lead to system ruptures or other dangerous scenarios. By allowing excess fluid to discharge, hydrostatic relief valves effectively mitigate risks associated with pressurization, ensuring that the system operates within its design specifications and maintaining safety.

While other aspects such as temperature control and liquid isolation are important in fluid management, they are not the primary functions addressed by hydrostatic relief valves. The focus remains strictly on pressure management, making their role vital in preventing overpressurization and subsequent system failures.
