Hello friends ,
i have a relay (driven at 5 v) ,driving a solenoid valve at 12 volts .
The problem is that it is in standing position and a metallic rod is inserted in it.when the relay is switched on it switches on the solenoid valve and the shaft is pushed up due to magnetic field, but when the relay is switched off the shaft doesnt comes back quickly , there is some delay in it .this is due to the fact that the current in solenoid is not decaying quickly on being switched off . Please suggest a solution for this problem ,i tried to put 1n4007 in reverse polarity across its terminals but not much use .
i am attaching the pics of the circuit as well as solenoid....
Any other practical ideas are welcome .
Thanks and regards
