OPERATION
The CP313-6 is a 20-size, load sense, priority, static, pressure compensator. The valve will provide
on-demand priority ow to port 2 in the required amount (dependent on the load sense pressure
on port 1), allowing the excess ow to go to auxiliary functions through port 4.
APPLICATION
Common applications include steering circuits that require pre-compensated, priority ow
to go to the steering system, and the excess ow will go to an auxiliary function, like a fan
motor. To obtain dynamic load sensing (priority type pre-comp) add in orice between ports
2 and 1 in the manifold. This provides faster response and is commonly used in steering to
ush out LS line. See Circuit Example.
