A stuffing box assembly comprises a housing including a main body, a tubular neck extending outwardly from the main body, and a housing flange extending generally radially outwardly from the neck and longitudinally spaced from the main body. A bore extends longitudinally through the neck and the adjacent part of the main body, and a slot communicating with the bore opens radially outwardly through the neck on the opposite side of the housing flange from the main body. A shaft is received in the bore for movement with respect to the housing, and an annular seal within the bore surrounds the shaft. The gland has a compression formation disposed at least partially within the bore adjacent one end of the seal and a flange joining the compression portion and extending laterally outwardly through the slot in the housing. The gland is movable toward the seal to compress it. An adjusting screw disposed generally parallel to the valve stem is threadedly connected to the flange on the gland and has an engagement formation, such as a screw head, abutting the side of the housing flange closest to the main body of the housing and engageable to rotate and operate the adjusting screw. |
