Abstract
Face valve apparatus having a plurality of valve stations each of which includes a replaceable pad that is behind and in contact with a planar face of a continuously moving valve section having a plurality of inlet ports in a circular array about a rotational axis for the movable valve section. Each of the valve stations are removably mounted to a fixed support by a plurality of fasteners that are accessible for operation from behind the support. Each pad defines an inlet port disposed in front of said support and operatively positioned so that for part of each revolution fo the movable valve section, each of the inlet ports communicates directly with the outlet port. When operation of certain of the fasteners releases a selected valve station from the fixed support, the selected valve station is removable from the support through an opening therein so that the pad is rearward of the support, where such pad is accessible for replacement without disturbing mounting of any of the other valve stations to the fixed support.
