Table 7 - Maximum Working Pressure
9.1.3 Maximum working temperature
The maximum continuous temperature that the valve can operate at
is determined by the temperature element(s) fitted to the valve. This
information is contained in Section 3.4, Table 2.
The element(s) in the valve may be subjected to slightly higher
maximum temperature for a short term period, the value for which is
also stated in Section 3.4, Table 2. The process fluid must be
reduced to the maximum continuous temperature within 30 minutes
however, or permanent damage to the element(s) may occur.
