The present invention features a retrofit, stop replacement device for the repair of damaged, rusted or corroded stop limits or abutments of distribution valves. The repair device is made up of a guide plate that fits over the facial portion of the distribution valve. Included in this guide plate is a replacement stop for the damaged, rusted or corroded stop abutment. This device is designed to be a one-piece unit. The guide plate is also made up of two inverted, U-shaped guide members that are positioned over the surface ribs of the distribution valve. The inverted, U-shaped guide members are held in place by their respective surface ribs. The ribs, via the inverted, U-shaped guide members, prevent the guide plate from being twisted when the rotatable valve abutment comes into contact with the stop abutment. The guide plate also includes at least one flange mounting bracket that is an integral part of the guide plate. The flange mounting bracket(s) fit flush upon the respective flange portions of the distribution valve. The respective flange mounting brackets are bolted to the flange portion by hexagonal stud bolts through stud holes that align with the bolt holes in the respective flange portion. Fastening the flange mounting brackets to the flange portion anchors the guide plate securely to the distribution valve.
