WHEN SETTING A VALVE INTENDED FOR USE AT HIGH TEMPERATURE
ON A TEST RIG USING A TEST FLUID AT AMBIENT TEMPERATURES, IT
IS NECESSARY TO SET THE VALVE AT SLIGHTLY HIGHER PRESSURE,
SO THAT IT WILL OPEN AT THE CORRECT SET PRESSURE UNDER
OPERATING CONDITIONS. THE NECESSARIES ALLOWANCE IS SHOWN
IN THE FOLLOWING TABLE.
