VALVE PRESSURE/
TEMPERATURE RATING
The pressure/temperature ratings given apply
to the valve only.
The maximum temperature at which a valve
may operate depends upon the sealing
compound with which the valve is filled.
However, should the sealing compound have
an operating temperature different to that of
the valve the lower temperature must apply.
