ZWICK is a leading manufacturer of valves which meet highest requirements and quality standards. The product range contains metal-seated butterfly valves known as series TRI-CON, the check valves series TRI-CHECK and the TRI-BLOCK series, ZWICK’s Double Block and Bleed Design.

The ZWICK self-centering disc design that is keyed to the shaft accommodates differential thermal expansions of the disc and the shaft. The triple offset geometry assures friction free running without radial loading of the seal ring and break-away torque. The TRI-CON series reaches a superior unrivaled life time cycle. For critical services a patented sealed bearing solution is offered to prevent fouling of the bearing associated with line media. ZWICK’s zero-leakage bearing design assures that no line media will migrate into bearings cavity. TRI-CON’s standard graphite packing meets all requirements of TA-Luft for fugitive emissions from the shaft and packing arrangements. All triple offset valves are certified according to Fire-Safe to API and British Standard.
