Abstract
A protective assembly for an operating nut of an actuator for a valve in an underground pipe system is comprised of a guide assembly and a mounting assembly. A riser pipe is used to access the operating nut from above ground. The protective assembly maintains alignment of the riser pipe at installation and as the ground shifts over time. The guide assembly is formed of a guide structure and a mounting collar that juts outwardly from the guide structure forming a flange. The mounting assembly has a first portion for attaching the mounting assembly to the flange, and a second portion for attaching the mounting assembly to the actuator.
