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 orice 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 orice 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.
