PCT No. PCT/EP90/00039 Sec. 371 Date Aug. 29, 1991 Sec. 102(e) Date Aug. 29, 1991 PCT Filed Jan. 9, 1990 PCT Pub. No. WO90/08282 PCT Pub. Date Jul. 26, 1990.A gate valve has a housing for a valve seat, and an attachment which extends outwardly from the housing and constitutes an extension thereof. A cap is secured to the attachment at the end of the latter remote from the housing, and a plate which traverses the attachment is held between the cap and the attachment. An externally threaded, non-rotary valve stem extends between the cap and the housing and passes through the plate. The valve stem meshes with an internally threaded, rotatable sleeve which receives the valve stem and is connected to a handwheel. The sleeve is at least partially confined by the cap and the plate, and both the cap and the plate are provided with bearing locations for the sleeve.
