A sanitary safety valve, made of stainless steel, is a device that releases excess pressure or temperature from systems like boilers to prevent accidents. These valves, also known as food-grade valves, are important for maintaining safety in systems that manage water and other substances in industries like food, dairy, and pharmaceuticals. They work automatically, are always ready for emergencies, and are preferred for their durability and ability to handle high temperatures and pressures. When selecting one, it’s crucial to consider the specific pressure and temperature it needs to handle.
