Proportional throttle valve
In order to alter the flow rate through the valve, the cross section of the throttle valve is electrically manipulated with the assistance of a proportional amplifier. The control voltage must be between 0 V and 10 V. The deflection of the slide is proportional to the applied voltage. At 0 V the valve is completely closed (in relation to the null overlap).
The hydraulic resistance relates to the completely opened valve. The overlap of the leading edges can be specified relative to the maximal slide distance.
Adjustable parameters
Hydraulic resistance: 1e-7 ... 100 MPa*min2/l2 (0.01)
Internal leakage: 0 ... 100 l/(min*MPa) (0)
