RD5000 PRESSURE DROP, RELIEF CURVE AND STANDARD FEATURES
The above drawing shows
a symbol for a Three-Spool Valve
Model Number RD532CCCAAA5A4B1
PARALLEL CIRCUIT VALVES:
Both the RD-5200 Two-Spool and RD-5300 Three-Spool
Valves are parallel circuit valves. When any one of the spools
is shifted it blocks off the open center passage thru the
valve. The oil then ows into the parallel circuit core making
oil available to all spools, If more than one spool is fully
shifted then oil will go to the spool with the lowest pressure
requirements. However, it is possible to meter the ow to the
spool with the least load and power two unequal loads.
