Automatic Metal Pressure Safety Valve

One of the most critical automatic safety devices in a pressure system is the pressure safety valve. The primary purpose of a pressure safety valve is the protection of life, property and environment during an over-pressure event in a pressurized vessel or equipment. An over-pressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure. A pressure safety valve is designed to open and relieve excess pressure from vessels or equipment and to re-close and prevent the further release of fluid after normal conditions have been restored.
