An improved valve, particularly adapted for use as a slurry valve, which includes a generally cylindrical valve body in sliding engagement with a generally cylindrical valve housing containing an inlet and a pair of spaced outlets. Separate passageways through the valve body are provided between the inlet and the two outlets. The position of the valve body is controlled by a fluid or gaseous actuator device adjacent one end of the valve body and spring means adjacent the other end of said body. Bearing surfaces on said valve body carry novel O-rings protected from wear and abrasion by the housing wall and the location of a pair of axially short annular inlet and outlet apertures. The specific valve design permits over-travel of the valve body when moved between operative positions while maintaining full fluid flow therethrough and simultaneous sealing of the alternate passageway. The novel seal-valve combination affords long life of the combination and prevents wear of the seal in this support valve design.
