Abstract:

A valve for controlling or diverting the flow of relatively viscous flowable materials such as polymers or the like. The valve includes a valve plug mounted for longitudinal movement within a valve chamber which receives the flowable material. A pair of antechambers flank the valve chamber, and a pair of portals connect the valve chamber with each antechamber. The valve plug selectably blocks one or the other of these portals, depending on the longitudinal position of the valve plug. A wall of each antechamber is angled to divert incoming flowable material toward the outflow passages individually leading away from the antechambers.
