3-way flow control valve
With sufficient pressure, the preset flow rate is kept constant in the direction of the arrow. The surplus hydraulic fluid is drained at connection T using a pressure compensator. The inlet pressure pA is load dependent, i.e. it changes with the outlet pressure pB. Therefore a parallel circuit of several 3-way flow control valves is not possible. In this case, the inlet pressures would be defined by the valve with the lowest inlet pressure. Compared to the 2-way flow control valve, the 3-way flow control valve is admittedly more efficient in its energy consumption.
The hydraulic resistance relates to the completely closed pressure compensator.
|Nominal flow||0 ... 500 l/min||1|
|Spring preload||0 ... 10 MPa||0.5|
|Pressure regulation range||0.01 ... 10 MPa||0.05|
|Hydraulic resistance||1e-6 ... 1000 bar.min2/l2||0.4|
