How to Find Maximum Valve Operating
Temperature
The maximum operating temperature for motorized valves
depends on the maximum ambient temperature at the valve
location, and on the maximum fluid temperature. Using the
graph in Fig. 2, find the maximum valve operating temperature
as follows:

1. Measure the ambient temperature at the valve and
locate that temperature on the ambient temperature
scale on the graph.
2. Draw a line from the ambient temperature, parallel with
the fluid temperature scale, to the maximum fluid tem-
perature line.
3. Draw a line from that point down to the fluid temperature
scale to find the maximum operating temperature. (Note
the example shown by the dashed line in Fig. 2.)
To find the maximum ambient temperature for a valve when the
fluid temperature is known, reverse this procedure.
