Critical Service Valves

Critical Service Valves

PTFE-lined flanged safety valves for corrosive media such as chlorine, acids, and lyes. With their highly resistant 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
