ABSTRACT:
A top operating telescoping adjustable valve box and valve stem assembly that incorporates a telescoping valve stem actuating system which, when coupled to a service valve, allows for the operation from ground level without the removal of a plug or lid. The system has a large range of vertical adjustability. The upper and lower sections of the assembly are in frictional connection with each other, which allows no transmittal of force to the lower section when any upward force to the upper section is applied, thus reducing damage to the buried valve and pipeline. The assembly provides a tracing block terminal, located on the top base, to allow for the connection of tracing wire from the valve top to the service pipe for service line location. The assembly also incorporates the placement of a tamper proof cap for the prevention of unauthorized operation of valve stem system.
