The PTFE lined bellows provide safe passage of pipeline. And also reduce the transfer of vibration from the rotation equipment connected to the glass assembly. Lined Bellows Serve both for sealing the conveyed media and for acceptance of the valve spindle motion.

PTFE's beneficial properties enable it to be used in a wide range of applications, such as seals (including PTFE 'O' rings), PTFE gaskets, valves, wire insulation, insulated transformers, bearings, surface coatings, chemical processing equipment, chemical transport and PTFE rubber diaphragms – to name but a few.
