    Here are pic's showing the difference between the EAS solenoid valve poppets and tubes.
    Type "A" is for the air springs.
    Type "B" is for the Inlet and Exhaust
    Type "C" is the Diaphragm Valve which is smaller than "A" & "B" valves

    Note that Type "C" poppet is grooved whereas Type "A" is not.

    Pic's show both ends of the poppets.

    I could not download full size pic's but if anyone wants them I can email a folder showing them, PM me for details

    Reviving this old post because I thought it was good place to ask.

    Does anyone know what the free length of the tiny springs for Inlet & Exhaust valve should actually be ? Mine are 13mm. They seem a little weak to me, so just wondering.

    I have never measured the springs, nor have I ever come across any that have lost tension. Mess with the springs at your peril.

    Nice find. This post should be moved in with @wammers EAS stuff.

    IrishRover hasn't been on for a while.

    Don't know the sizes, but I've done a couple of blocks and yes they are very..very.. light springs.

    I doubt the springs are worn. Measure them they should all be the same length. The only possible places were a leak from a corner can occur in the valve block providing the pipes are sound is the seat seal on the solenoid shaft or the small O'ring under the seat. The seat seal can be removed resurfaced and shimmed back in to give a slight protrusion.
