A safety valve is a device designed to protect equipment and systems from excessive pressure. It automatically releases pressure when it exceeds a predetermined limit, preventing potential explosions or damage. Safety valves are commonly used in various industries, including oil and gas, chemical processing, and power generation. These valves work by opening at a specific pressure, allowing gas or liquid to escape safely. Once the pressure drops back to a safe level, the valve closes again. This mechanism ensures the integrity of systems like boilers and pressure vessels, making safety valves essential for operational reliability and safety.
