Safety Valves (also known as pressure relief valves or safety relief valves) are devices designed to automatically release excess pressure from a system to prevent equipment failure or accidents. Commonly used in industries like oil and gas, power generation, and chemical processing, these valves ensure safe operation by maintaining pressure within safe limits. Safety valves are essential for protecting systems, equipment, and personnel in high-pressure environments.
