2-Way Flow Regulator, Pressure Compensated
Technical Features
Functional Description
Technical Data
Characteristics measured at ν = 32 mm

/s (156 SUS)
› Set ow rate independent of load pressure and temperature changes
› Adjusted ow rate depends on the orice area and adjusted differential pressure
› Hardened precision parts
› High ow capacity
› Quiet and modulated response to load changes
› Used in meter-in, meter-out, or bleed-off applications
› Wide range of ow rate options
› Adjustable by allen key or hand screw, optionally sealable (lockwire holes)
› In the standard version, the valve is zinc-coated for 240 h protection acc. to ISO 9227
This pressure compensated, hydraulic ow regulator in the form of a screw-in cartridge with xed orice and
variable spring setting is designed to control ow rates independently of pressure and temperature, especially
in systems where only small movements due to load changes are required. The flow rate stabilization is
provided by a pressure compensator in the direction from 1 to 2. The valve will maintain the set ow regardless
of pressure variations on the regulated or inlet port.
In ow direction 2 - 1, the valve works as an ordinary throttle valve without pressure compensation. The
regulated ow increases with clockwise rotation of the adjustment screw and descreases with
counter-clockwise rotation. The desired settings can be locked down.
