3-Way Flow Regulator, Pressure Compensated
Functional Description
Technical Data
Characteristics measured at ν = 40 mm
2
/s (195 SUS)
A fixed-orifice, pressure compensated hydraulic flow regulating valve in the form of a screw-in cartridge with
variable spring setting. It can be used as a priority flow regulator or a 2-way flow regulator when the by-pass
port (2) is blocked.
This valve maintains a constant priority flow from port 1 to port 3 based on the adjustment, regardless of
pressure changes downstream on port 3. Excessive flow is directed to port 2.
Technical Features
› By-pass flow regulator, set flow rate independent of load pressure and temperature changes
› Adjusted flow rate depends on the orifice area and adjusted differential pressure
› Hardened precision parts
› High flow capacity
› Quiet and modulated response to load changes
› Used in meter-in applications
› Wide range of flow rate options
› In the standard version, the valve is zinc-coated for 240 h protection acc. to ISO 9227
