For sale is a Gresen Hydraulic Spool Valve Dump Truck or Semi 599S 3100H. It is just two sections of it that fit each other, but they are separated physically and there is no seal between them. They need another section or a plate to seal the other side of the thin section to make a complete valve. This has been in storage for a long time and has acquired a little storage rust. However, in my opinion, I don't think it has ever been used because there is no evidence of attachment or mounting on the silver screw holes. They are clean. If you receive this item and you don't like it for any reason, you are welcome to return it. You would just pay ALL shipping. Thanks.
