PTFE bellows are used as balancing elements between engineering parts, which is widely used in chemical, food and medical appliances. The different geometres of the folds highly flexible or pressure-resistant versions can be designed and manufactured to reach higher flexibility or compressive strength.  External and internal Pressure, number of runs and all-closed/ all-open lengths are the critical factors to consider in designing a bellow.

Whether your PTFE bellow requirements are simple or complex, our experts have the ability to customized Design and Performance.

Type of PTFE Bellows

• • Round folds bellows: Medium pressure stresses, Easy to clean.
  • Angular folds bellows: High rigidity and allows only short stroke. Easy to clean, Stable walls and both vertically and horizontally mounted.
  • Sharp folds bellows: Low-pressure stresses and high stroke frequencies. Good installation length to elasticity ratio. Well suited for use in dynamic applications.
  • Bellows with metal inserts: In order to introduce higher forces into PTFE bellows, a metal part is often insert.

Applications of PTFE Bellows

• • In solenoid valves
  • For filling systems
  • In aseptic valves
  • In metering deveices
  • In pumps and valves
  • As compensation for expansion in pipe systems
  • For shielding sterile areas
  • Coating technology
