Product Description

PTFE lined ball valves feature a robust metal pressure-bearing body (carbon steel, stainless steel, etc.) with the entire flow path and ball fully lined with PTFE and other fluoroplastics. This full fluoropolymer lining completely isolates the metal substrate from corrosive media, delivering exceptional universal chemical corrosion resistance against strong acids, alkalis, oxidants, chlorine media and organic solvents.

The PTFE lined ball valve opens and closes via 90-degree ball rotation, providing bubble-tight soft sealing, low flow resistance and quick operation. It is a dedicated main shut-off valve designed specifically for severe corrosive chemical pipelines, available in floating ball straight-through design with manual, worm gear, pneumatic and electric drive options for automated process control.

PTFE Lined Ball Valve

Product Features

Unique seal seat design The cantilevered lip is made by the first contact between the ball and the sealing seat, which creates a buffer zone between the valve body and the sealing ring, which can automatically compensate for the wear of the valve seat, sharp changes in temperature and pressure, and plastic deformation Leakage; improved sealing performance and extended service life.

Design of no leakage at the connection end The connection parts of valve body and valve cover, PTFE Lined Ball Valve body and packing are sealed by gasket, in order to prevent the leakage of the connection parts caused by various factors such as high temperature or vibration, it is specially designed as The metal is in contact with the lining to form a fixed-end flange to ensure no leakage.
