Logic Elements Technical Information
Spool Type
CP700-1
OPERATION
The CP700-1 is a 10-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.
