Bypass pressure compensator assembly
CAPACITY: 60 L/min.
Bypass pressure compensator
This valve assembly consists of a normally-closed bypass style compensator on the P port and a shuttle that
senses pressure from the higher of the 2 work ports. Its purpose is to provide a relatively constant pressure drop
across the directional valve thus isolating the directional valve spool from high flow forces. This is accomplished by
bypassing the excess oil to the T port. The constant drop creates a pressure compensated flow control out of the
directional valve.

TECHNICAL DATA
Capacity 60 L/min.
Body Type Sandwich
Interface ISO 03
Body Features Meter in P
Model Weight 0.70 kg.
Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port
type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port
type/size specified.

TECHNICAL FEATURES
This assembly is meant to be used in a single station circuit with a fixed displacement pump.
The pressure differential across the orifice (directional valve) varies with bypass flow and system pressure. It is at its lowest at zero bypass flow and increases with
increasing bypass flow and system pressure.
Another term for this assembly is a hydrostat.
