Span Your Valves
Chapter 9
9-14
Span your clamp close velocity (flow) valve(s) for optimum velocity
performance. Do this in three parts:
Confirm critical values
Span your clamp close velocity (flow) valve(s)
Test valve linearity with a velocity vs. position profile
Important: You may omit this section if you have the right information on
valve spanning. Many injection molding machine OEMs and hydraulic
valve manufacturers provide data on spanning the working range of valves
used on their machines. If this information is available from your OEM
for your machine’s clamp close velocity valve(s), enter the values into
velocity control limits FCC45-48, SCC45-48, and TCC45-45 and proceed
to Span your Open Slow Valves.
Confirm Critical Values
Important: Confirm that your entries for configuration values (chapter 7)
and profile values (chapter 8) for clamp close profiles are as follows:
