Double acting relief valve cartrage part# 311719 for a 1998 Putzmeister TS2070 so far the only one known to exist is currently located in Brazil..... Anybody know of any more out there? apperently this sucka is a rare find. like main bearings for a 95 Husqvarna dirtbike..... needle in a haystack.

Try calling Alex Wagner in Paterson NJ. Alex in most cases can pull a rabbit out of a hat.

Great people

Mike Wagner is the MAN! I have searched for this part for weeks. He located the part in a few hours and I should be back up and running by the end of the week. Thanks to Wagner thank you concreteluvr and Thank you concretepumping.com for help in bringing us together.
