I have a pneumatic solenoid valve shown **broken link removed**.
The black box on the end is the coil and when it energizes it pulls a rod in the middle of the assembly. Once its starts pulling air pressure opens it up faster.
The highest cycling time I can get is 60ms (you can see this here). I need it to be really fast, like less than 1ms cycling time.
Is there a way using external circuitry to decrease the energize time?
I just going out on a limb here and thinking that adding some resistance in series with the coil will lower the time constant, and therefore decrease the energize time. Oh course I could be wrong.
Thanks for your input and time!
The reason for the faster times is for possible position control of the pneumatic actuators. I read somewhere (I think an IEEE report) that you can control position using PWM to the valves. What ever the duty cycle is, that will be the position of the pneumatic rod. The frequency determines the position ripple, but the frequency is limited to the frequency that the solenoid valve can handle.
