I'll post pictures and dimensions tomorrow morning. I recall the seal being 1" OD, .75" ID and .103" wide, but I'll make sure before I post the pictures. Instead of shuttle, I think I meant to call it a bobbin which actually may be a hydraulics term. The valve body has a .43" diameter rod which has a short 1" diameter piston screwed to each end. Each piston is driven by a solenoid. I need the two piston seals. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
