Description
A spring safety valve is a device used to automatically reduce excess pressure in systems, preventing it from exceeding established safety limits. It consists of a valve, a spring, and a setting that determines the valve's opening pressure.
When the pressure in the system reaches a certain level, the spring activates, opening the valve and allowing excess pressure to escape, preventing damage to equipment or the system due to overpressure. Spring safety valves are widely used in various industrial and technical systems to ensure their safety and reliability.
