What is the purpose of a hydrostatic relief valve in an LP Gas storage facility?

The purpose of a hydrostatic relief valve in an LP Gas storage facility is to relieve excess pressure. This component is crucial for maintaining safety within the system. In the event of overpressure conditions, which can arise from temperature increases or other factors, the hydrostatic relief valve activates to release pressure. This prevents the storage tank from reaching critical limits that could lead to catastrophic failures such as tank rupture or explosion.

By allowing gas to escape safely, the hydrostatic relief valve helps maintain the system's integrity and ensures compliance with safety regulations. In storage facilities, where large volumes of LP gas are held under pressure, having a reliable method to relieve excess pressure is essential for protecting both the equipment and personnel working in the facility.

The other choices do not align with the primary function of the hydrostatic relief valve: it does not increase system pressure, regulate gas flow, or monitor gas levels. Each of those functions is managed by different components or systems within a propane storage facility.
