Things you should know about Safety valves
Safety valves are protective devices for boilers. The pressure vessels and pressure pipelines prevent pressure in the pressurized equipment from exceeding the design. Since the safety valve can operate independently of any external energy source, it is the last protective device for pressure equipment. In this sense, according to the safety valve manufacturer , no other protective devices replace it. When you find an abnormal increase in the pressure of the medium for some reason & reach the pre-set value, the safety valve automatically opens and then discharges to prevent the pressure from continuing to rise. Then the reduction in the medium pressure due to the discharge of the safety valve or reach of another predetermined value, the valve automatically closes, preventing the medium from continuing to discharge. The valve remains closed and sealed when the medium is at normal operating pressure. It automatically opens and closes according to the working pressure of the pressu
