Abstract: A guard for a valve upon a buried fluid line prevents earth entering the opposed arches or the bottom of a conventional casing during installation about and above the valve permitting access after filling of the excavated cavity for the fluid line. Alignment of the casing with the valve and the fluid line is also facilitated with an upward facing bore of an upward extending upward portion of the guard which permits insertion of the end of a length of conduit during installation and allows passage of the end of a wrench in operation of the buried valve. A longitudinal cavity open at the bottom and ends and continuous with the bore is defined by a lower portion of the guard. Opposed ends extend into the opposed arches of the casing, protect the fluid line from a descendant arch, and serve as guides for casing disposition. Two lateral pairs of stabilizers extending outwardly from either end stabilize the guard with respect to the casing and the fluid line.

Abstract: A valve cover for enclosing an underground area surrounding the actuating mechanism of a flow control valve. The valve cover includes a body having a structure configured to position the valve cover in a desired orientation relative to the flow control valve. This positioning structure may be at least partially elastomeric, and configured to resiliently deform and urge against the flow control valve when the valve cover body is placed over the valve actuating mechanism. This maintains the valve cover body seated in a centered, leveled orientation relative to the valve actuating mechanism. The positioning structure may also be formed as a spacer configured to contact the valve actuating mechanism itself and space the actuating mechanism from the valve cover body. The valve cover body is configured so that, when it is installed, a valve tool may be freely inserted into the enclosed underground area and operatively engaged with the valve actuating mechanism.
