Two way valves with different opening characteristics and motor

Information

Test model for two way valves. Note that the leakage flow rate has been set to a large value and the rangeability to a small value for better visualization of the valve characteristics. To use common values, use the default values.

All valves are connected to a model of a motor with hysteresis. A more efficient implementation that approximates a motor but lacks hysteresis would be to set the valve parameter use_strokeTime=true instead of using the motor model.
