Stationary and sliding refractory valve bodies of a sliding closure unit, for use in controlling the discharge of molten material from a vessel, are mounted on respective support frames to be precisely centered with respect thereto and to prevent the application to the refractory valve bodies of stresses due to such mounting during operation of the unit. At least one bore hole and at least one elongated groove are formed in the refractory valve body. First and second rods are fixed to the respective support frame and extend therefrom into the bore hole and the groove, respectively. The bore hole is centered on a longitudinal axis of the groove extending in the direction of elongation thereof.
