Bellows
Variety that inspires.
Bellows made of high-performance materials are used, for example, as compensating elements between structural parts.
Through the targeted use of different pleat geometries, any properties between highly flexible and pressure-resistant can be achieved.
The outstanding properties of our materials enable you to use bellows efficiently and effectively in the food & pharma, life science and medical technology sectors, as well as in many other applications.
The following bellows versions round off our versatile range of bellows:
- Bellows with tapered, chipless pierced folds for the greatest possible stroke and low pressures up to 3 bar.
- Bellows with round, twisted folds for easier cleaning and maximum flexural fatigue strength as well as low to medium pressures up to 6 bar.
- Bellows with solid, twisted folds for high pressures above 6 bar. Ideal with angular support on the rod or in the cylinder bore.
Advantages
- FDA conformity for food and pharmaceutical products
- High thermal resistance: -60 °C to +200 °C
- High chemical resistance
- Anti-adhesive behavior
- Very good sterilizability
- Economically sophisticated series production from semi-finished product to end product
Types
Bellows for solenoid valves
The bellows for solenoid valves is characterized by its high flexibility and enables a high frequency. Thanks to its physiological harmlessness and resistance to aggressive cleaning agents, this bellow is used in medical technology in particular.
Bellows for filling valves
The bellows for filling valves guarantees hermetic separation of the medium from the actuating mechanism. The tip of the bellow is also the sealing cone of the valve.
Bellows with metallic insert
A bellows with a metallic insert enables a detachable connection with drive and connection elements. This can reduce the flow of material in valve seat areas, for example, by providing wide-area support, thus enabling sustainable tightness at the highest contact pressures. A wide range of geometries and degrees of automation are available to create threaded connections that are optimized in terms of cost and use.
Bellows with multifunction
The bellows with multifunction is suitable for separating two areas with moving parts. It is used, for example, for the integration of sealing and guide elements. Connections can be manufactured to customer specifications.
Bellows made from two materials
The bellows are used in the food and chemical industries. The combination of two materials increases the wear resistance and stability of the bellow. Our material combinations ensure that deformation is minimized and enable the integration of connecting threads.
