The primary function of a relief valve is to prevent overpressure conditions that can occur in various systems, such as boilers, pressure vessels, and piping networks. When pressure builds up beyond the safe limit, the relief valve opens, allowing the excess fluid or gas to escape. This action not only prevents potential explosions but also protects other sensitive components within the system. Without relief valves, the risk of mechanical failure or hazardous situations increases significantly, posing threats to both personnel and equipment.
