Fully opened
The CP702-4 is a 16-size, normally open, pilot-to-open, spring-biased
dierential-sensing logic element. It will modulate ow from 2 to 1 based
on the spring control pressure, inlet pressure at port 1, and outlet pressure
at port 3.

Spool Type
Common applications include: pre-compensator for proportional directional
control or ow controls, as well as a pressure control valve. A common application
for this valve is as a pressure compensator when applied with a xed, or adjustable
orice to create a pressure-compensated ow control. This ensures that ow rate,
and resulting actuator speed is maintained regardless of pressure drop across the
control orice. Eective use of logic elements is a key to designing cost-eective
circuits, and is limited only by the imagination of the designer.
