V Nominal Pressure Code of Safety Valve
Nominal pressure code shows in Arabic numerals,
its value is 10 times of the value of nominal pressure with the
unit of Mpa.
When labeling operating temperature and
pressure, operating pressure should use P to show, and at right
lower corner attaches max temperature value, which is the integer
of the result of 10 dividing max. temperature value of the medium,
e.g.£ºvalve of the working temperature of 540¡æ and operation pressure
of 10Mpa has code of P54100.
