OPERATION
The CP702-1 is a 16-size, normally-closed, pilot-to-close, spool-type,,
spring biased dierential-sensing logic element. It will modulate ow
from 1 to 2 based on the spring control pressure, inlet pressure at
port 1, and pilot pressure at port 3.
APPLICATION
Common applications include load-sensing bypass compensator for a
xed displacement pump with single or multiple actuators as well as
bypass-type pressure-compensated ow control. Eective use of logic
elements is a key to designing cost-eective circuits, and is limited only
by the imagination of the designer.
