PN16 304 Threaded Safety Pressure Relief Valve
The primary purpose of a safety valve is the protection of life, property and environment. A safety valve is designed to open and relieve excess pressure from vessels or equipment and to reclose and prevent the further release of fluid after normal conditions have been restored.
A safety valve is a safety device and in many cases the last line of defence. It is important to ensure that the safety valve is capable to operate at all times and under all circumstances. A safety valve is not a process valve or pressure regulator and should not be misused as such. It should have to operate for one purpose only: overpressure protection.
For Spring Loaded Safety Valve,the spring force is transmitted via the spindle to the plate closing against the nozzle, which together with the plate closes the process and ensures sealing. This condition is maintained as long as the spring force is greater than the force generated by the pressure at the valve inlet.
