    5/5/2009 · Depending upon the design pressure of boiler, the various safety valves in the boiler are set to open at a particular pressure called the "set pressure." Until the system pressure reaches the set pressure, the valve will not open or leak. This is achieved by the safety valve designers by adopting a patented disk design.

  • Safety Valve | Function,types, Construction,Working

    Safety valve is used to guard the boiler against the excessive high pressure of steam inside the drum. If the pressure of steam in the boiler drum exceeds the working pressure then the safety valve allows blow-off the excess quantity of steam to atmosphere. Thus the pressure of steam in the drum falls. The escape of steam makes a audio noise to
