What does PVSV in a distribution box mean

The abbreviation PVSV stands for Pressure Vacuum Safety Valve, which is a device designed to maintain safe pressure levels in storage tanks by allowing vapor to escape or preventing excessive vacuum pressure from forming, thus ensuring the integrity of the tank. PSVs are automatically activated when the internal pressure exceeds a set limit, ensuring that the equipment's pressure. It is based on published sources but should not be considered for the detail design and. Ensuring the proper protection of a chemical or oil and gas plant from overpressure is one of the major jobs of a process engineer.
