Compactor Owner’s Manual
Carrier without Auxiliary Circuit
If the carrier does not have an auxiliary control valve (see Figure 2), a
priority flow control valve must be installed to direct oil flow from the
normal circuit to the compactor. The priority flow control valve is usual-
ly equipped with a flow adjustment and pressure relief.
These auxiliary control valves often need a check valve on the regulated
port to completely close the flow. If too much flow is divided, excess
heat is generated in which case the oil needs to be cooled.
