This is a new slide valve arrangement, it includes a housing having a longitudinal axis and a disc valve or gate movable by external hydraulic or mechanical actuator. The gate slides along a first surface of a guide member. There is a throat member through which the material to be regulated is directed. The throat and housing support a fixed plate. The guide member is held in position by a column support between the housing and the upper side of the guide. The guide member is held on the underside by a securing bar supported by gusset supported from the housing. The guide member is held against lateral movement by bolt extending through the guide member and screwed into a removable bolting bar which is positioned by a stop block which is secured to the gusset. Shim means are provided to adjust the vertical clearance between the throat and the gate and horizontal clearance between the gate and the guide member.
