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

/s (156 SUS)
› By-pass ow regulator, 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 responsed to load changes
› Used in meter-in 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
A xed-orice, pressure compensated hydraulic ow regulating valve in the form of a screw-in cartridge with
variable spring setting. It can be used as a priority ow regulator or a 2-way ow regulator when the by-pass
port (2) is blocked.
This valve maintains a constant priority ow from port 1 to port 3 based on the adjustment, regardless of
pressure changes downstream on port 3. Excessive ow is directed to port 2.
