4.4 Aligning the travel
indication scale
The travel indication scale has two opposed
scales. Which scale is to be used depends
on the valve version (Fig. 3). In the delivered
state, the scale alignment applies to globe
valves and three-way diverting valves. The
alignment needs to be changed when a
three-way mixing valve is used (see below).
