Model No.: 7
PTFE ball is a unique product.
It has many advantages in applications where metals or alloys can not be used.
Broad operating temperature(-400°F to +500°F)
chemical inertness to most corrosive liquids or gases
extremely low coefficient of friction.
PTFE balls are highly functional in self lubricating conditions such as ball bearings.
In the fluid handling industry PTFE balls are used in ball valves that have contact with extremely corrosive liquids.
The PTFE ball has reduced maintainance costs and man hours in the field by eliminating the replacement of valve components subjected to corrosive environments.
