resistors to make valves multi speed?

when the exciter fails the valve fails nuetral, a valve is either open or closed. if you limit the voltage it just wont operate. but by all means try it out

That's why I just use these:



sure they're ugly but I can control it exactly how i want.

yeah, if the dumps get stuck open....but thats due to an o-ring slipping...to my knowledge...but i could be wrong aaron, which i prolly am

damn i knew i couldnt prove a engineer wrong!

im gonna be a good engineer huh? haha

The Slam Specialties DSV valves are dual speed valves, and I don't think you actually need the digital controller to use them, just some extra wiring and an extra switch or two.

The way they slow down solenoids is to pulse them on and off really fast.

^^^Pulse width modulation (PWM)^^^^Fully on 12V for extremely short bursts at a time but if fast enough will actually only give the impression of 5volts, 8volts, etc...

huh?

It doesn't take very high amperage to pull a electromagnet.Asco valves will pull at less than six volts,one amp.The problem is that most valves have the same pressure on both sides of the diaphram and use a soft spring leaving a delay when closing.I messed with this a little and my car was grounded on the third pulse.

damn. figured the thought wouldnt hurt. could always just run a front and rear 1/4" dump valves on a seperate switch and have it tee'd in parallel.
