Product Summary

A safety valve is a valve mechanism made to release the substance from boilers, pressure vessels, or other system when the pressure or temperature exceeds preset limits. It is part of a bigger set named pressure safety valves or pressure relief valves (PRV). The other parts of the set are named relief valves, safety relief valves, pilot-operated relief valves, low pressure safety valves, vacuum pressure safety valves. A pressure relief safety valve is the valve used to release the pressure. It is a very important part of the equipment. A pressure relief safety valve is also a safety device designed to protect a pressurized vessel or system during an overpressure event. An overpressure 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 (MAWP) Since pressure relief safety valves are safety devices, there are many Codes and Standards. The maximum inlet pressure (Primary pressure) is 0.7MPa (For JIS 10K standard). The pilot valve operates and the main valve is opened to release the excess pressure to the outlet side and maintain the inlet pressure at the set pressure. The set pressure can be finely adjusted with the coil spring of the pilot valve. The main material for the valve is metal, usually brass, which can further maintain good properties for the valve.
