Our valve control unit is a piece of hardware of a driver unit for automotive solenoid valves for test purposes. Application of these valves is typically controlling the fuel pressure and flow in an automotive combustion engine. The name of this driver unit is ValDino, which is the abbreviation and minimization for Valve Driver.
ValDino system may be used to define load profiles and control the activation and stress of up to 8 solenoid valves parallel and independently.
The main purpose of ValDino is applying currents to solenoid valves. Generally, the applied current is defined by toggling the output at a specified duty cycle. A minimum inductance of the load is required. Depending on the valve type different current waveforms are used:
