Zwick TRI-CON Valves

Zwick’s TRI-CON valve employs a self-centering disc that is keyed to the shaft, not pinned.  Other TOS valve manufacturers permanently pin or affix their discs to the shaft.  To accommodate for differential thermal expansion of the shaft and disc, other manufacturers must rely on a seal ring that compresses radially.  This makes their designs subject to jamming due to thermal expansion.
