ABSTRACT:
A three-way valve comprises a cylindrical valve chamber with a pair of axially spaced ports on one side and a third centrally located port on the other side. A valve disk on an axial valve rod is movable between positions on opposite sides of the third port to control communication between the ports. The chamber includes liner sleeves between which the valve disk moves and against the inner ends of which the disk bears in its respective positions. The sleeves support the disk against fluid pressure forces resulting from flow between the ports, and an effective seal is provided between the disk and the respective sleeve.
