Spring Set 
The Spring Set box shows information about the spring forces in the actuator. 
Spring Initial is the pressure required to initially move the valve as the valve is beginning to 
compress the spring. 
Spring Final is the pressure required position the valve at the end of travel where the spring 
is fully compressed. 
Spring Rate is the average force divided by the distance traveled during spring 
compression.
