SPRING RANGE MATRIX

The spring range matrix provides the theoretical spring ranges from

a given spring arrangement and valve stem travel.

You are encouraged to discuss your application with one of the

Powers application engineers.

In general, positioners are required to sequence valves. In some

circumstances it may be possible to sequence valves by changing

spring ranges and adjusting start points (preload adjustment).

Again, please consult with one of our application engineers for

assistance.
