Span Your Valves
Chapter 9
9-47
Span your clamp open velocity (flow) valve(s) for optimum velocity
performance. Do this in three parts:
Confirm critical values
Span your clamp open velocity (flow) valve(s)
Test valve linearity
Important: You may omit the next two parts of this section if you have
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 open velocity valve(s), enter the
values into velocity control limits FCC45-48, SCC45-48, TCC45-48, and
OSC45-48 and skip to Span Your Injection Pressure Valve.
Confirm Critical Values
Important: Confirm that your entries you configuration values (chapter 7)
and profile values (chapter 8) are as follows:
