The CP701-1 is a 12-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.
Rated pressure 210 bar [3000 psi]

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.
