OPERATION
OPERATION
The CP701-4 is a 12-size, normally open, pilot-to-open, springbiased dierential-sensing logic element. It will modulate ow
from 2 to 1 based on the spring control pressure, outlet pressure at
port 1, and pilot pressure at port 3.
APPLICATION
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 orice to create a pressurecompensated ow control. This ensures that ow rate, and resulting
actuator speed is maintained regardless of pressure drop across the
control orice. Eective use of logic elements is a key to designing
cost-eective circuits, and is limited only by the imagination of the
designer.
