30 years experience in design and production of valves guarantee high standard products. ZWICK valves are produced state-of-the-art. The triple offset butterfly valves are specially designed for critical services where they are used as shut off and control valves. The in-house design enables offering customized solutions for individual applications like the global Industries of Oil and Gas, Chemical, Petrochemical, Energy, Offshore and Steel. TRI-CON valves incorporate a unique third offset design with a true cone-in-cone seating and a reliable zero-leakage performance and allow bi-directional tightness.

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.
