ABSTRACT:
A valve housing has a valve seat surrounding a fluid passageway, a valve closure member cooperating with the valve seat to close the passageway. A valve actuating spindle for controlling the position of the valve closure member extends through a tubular part of the valve housing, the end of the tubular part remote from the valve seat forming itself a housing for a gland seal. The wall of the tubular part at the inner end of the gland housing is displaced radially inwardly to form, within the tubular part, an annular constriction which surrounds the spindle with a clearance and which forms an abutment towards which an annular packing within the gland housing is urged by a gland fitted to the outer end of the gland housing, to seal the spindle to the valve housing.
