The Response time (Rt) of a solenoid valve is the elapse period between the energisation (or de-energisation) of the
coil and the moment where the outlet pressure reach the 50% of the peak.
Example of a circuit test:
The response time depends from the type of valve, from nature of the media, from the pressure and from the current
(AC or DC), if it’s considered the moment of electrical connection or disconnection
