Valves for chemical and petrochemical applications
Besides the fact that this design prevents any media from entering into the bearing cavity the advantageous design to minimise shaft deflection of Zwick's standard bearings can be kept in the special design Another plus is the fact that every standard Zwick valve can be upgraded with the Sealed Bearing

Cryogenic Triple
Cryogenic Triple-eccentric Metal-seated Butterfly Valves Overview The Triple-eccentric design:shaft from the centerline of sealing surface to form the 1 st eccentric the shaft offsets from centerline of pipeline to form the 2 nd eccentric and the scalene cone form the 3 rd eccentric This design can make iffectively use of the cam effect and completely eliminate the friction between the seat
Zwick – AC Valves
The Zwick Triple Offset valve can answer isolation problems in many processes and applications Initially designed as a steam shut off valve the Triple Offset valve is now accepted as a direct replacement for Gate Globe and Ball valves where tight shut off is required at elevated temperatures or space and weight savings are a consideration
Sealed bearing prevents failures in Triple Offset Valves
The company Zwick located in Germany is the manufacturer of the TRI-CON series and is one of the most respected manufacturers of metal seated Triple Offset Valves in the world today Since founding the company in 1977 Mr Hans Zwick owner and managing director has overseen the expansion of the company and product range
Triple Offset Butterfly Valves 150 to 2500lb
The seat and seal are designed conically and on centre This design relies on a frictional interference seal and so is applicable only to soft seated valves Triple Offset The centreline of the cone is rotated away from the valve centreline resulting in an ellipsoidal profile and providing the third offset With this geometry seat seal
The Tri Lok Advantage
the seat and seal is very important in a triple offset butterfly valve and often an overlooked factor in valve design and selection While the technical advantage of the third offset in a triple offset valve is to reduce and almost completely eliminate friction a difference in hardness is still required to avoid

Zwick for Molten Sulphur or Sulphur Tail Gas
The Zwick Tri-Con series valve is a triple offset valve with true cone in cone design which totally eliminates any rubbing of the seats hence eliminates any wear and tear which would generate leakages across the seat this is technically not possible for other typical high performance valves which means it is limited to a double eccentric
TriLok Triple Offset
