CRITICAL SERVICE
PTEE-lined flanged safety valves for corrosive media such as chlorine, acids, and lyes. With thier highly resitant lining they offer a safe solution for corrosive media.
|
ADVANTAGES
PTFE parts in different designs for optimized resistance to highly-corrosive media Economical alternative to high-alloyed materials Carrier gas blanketing using double-walled pipes is possible.
