Abstract
A gate valve has a housing, a valving element in the housing, and a seat in the housing which cooperates with the valving element and extends transverse to the flow direction. The valving element is carried by a spindle which serves to move the valving element into and out of engagement with the seat. A support for the spindle is disposed in the housing and has a central, outwardly directed flange which defines a passage for the spindle. The flange is coupled to the spindle in the region of the valving element so that the support moves with the spindle. The support is in sliding engagement with the internal surface of the housing to thus guide the spindle and support the latter against transverse forces generated by flow through the housing.
