PTFE Bellows
serve both for sealing the conveyed media and for acceptance of the valve spindle motion. Such non-stuffing box types with PTFE bellows are used as isolating, metering, servo and conveyance valves. Pumps, agitators, centrifuges, filling and weighing units can be installed in equipment and piping systems of steel, enamelled steel, glass and plastic, free from vibrations and shocks due to PTFE bellows. This flexible adapter at the same time ensures the compensation of axial, lateral and angular movements. PTFE bellows are produced by machining of a particularly high-quality semi-finished material - owing to the high requirements in chemical, mechanical and thermal applications.

|
Design according to customer specification (works test certificate/ works certificate). These material combinations are also approved by BGA/FDA (except medical applications). For positive power transmission between valve spindle and PTFE bellows, it is possible to sinter threaded metal sleeves directly into PTFE.
