About Safety Valve:
------------------------------------------------------------------------------------------------------------------------------------------------- 
A safety valve is a valve that acts as a fail-safe in a thermal-hydraulics plant. An example of safety
valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, 
pressure vessel, or other system, when the pressure or temperature exceeds preset limits. 
Pilot-operatedreliefvalves are a specialized type of pressure safety valve.
Safety valves were first developed for use on steam boilers during the Industrial Revolution. Early
boilers operating without them were prone to explosion.
Vacuum safety valves (or combined pressure/vacuum safety valves) are used to prevent a tank from 
collapsing while it is being emptied, or when cold rinse water is used after hot CIP (clean-in-place)
or SIP (sterilization-in-place) procedures. When sizing a vacuum safety valve, the calculation method
is not defined in any norm, particularly in the hot CIP / cold water scenario, but some manufacturers 
have developed sizing simulations.
