3-Way Pressure Compensator, Spool-Type, Direct-Acting
Technical Features
Functional Description
Technical Data

/s (156 SUS)
The characteristic of the pressure compensator corresponds with the flow rate of a PRM2-043Z11/12
and PRM2-063Z11/30 proportional directional valve.
If the pressure resistance increases due to a flow rate increase, the pressure differential also has to increase in order to ensure correct regulation.
Flow Q [l/min (GPM)]
Pressure p [bar (PSI)]
› The valve keeps the pressure drop between the inlet and the pilot connection at a constant level
› Used as a load sensing valve with proportional directional and flow valves to control the flow rate
independently of pressure variations
› Excellent stability throughout flow range with rapid response to dynamic pressure changes
› Spring setting of the variable adjustment compensator can be varied from 5 to 40 bar (72.5 to 580 PSI)
› Quiet and modulate response to load changes
› Hardened precision parts
› High flow capacity
› In the standard version, the valve is zinc-coated for 240 h protection acc. to ISO 9227
A normally closed, direct-acting, spring loaded pressure compensator valve in the form of a screw-in
cartridge.
From the outlet of the controlled directional or proportional flow valve a load sensing signal is taken to
the spring chamber of the pressure compensator port X.
Typically, 3-way pressure compensators are used as meter-in regulators in parallel with flow restrictor
valves when raising or lowering variable loads at the same velocity is required.
The pressure compensator valve then keeps the pressure difference between its pressure inlet and the
pressure at the output port of the regulated flow valve nearly constant.
When the pressure differential exceeds the pre-set value, the pressure compensator opens and releases
excessive flow from the main circuit to port B. If there is no flow demand from the consumer, the
compensator allows the oil to flow back to tank and therefore vents the whole system. This prevents the
hydraulic system from overheating especially in load sensing circuits with a fixed displacement pump.
