  • Rancillo S24 adjusting the OPV

    I thought I would start a new thread just in Case someone is searching for this information,

    S24 and most likely other S models come from the factory with a non adjustable OPV set at 12 bar

    but you can take them apart and remove 3 of the 4 small ss washers inside at the BACK of the spring to bring it down to 9 Bar as I did.

    I found this by trial and error using the gauge I rigged up. also thanks to Jimmytheboot for the drawing and pointing me in the right direction.

    here are some pics.
