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.
