Class 150 / 300 / 800 Regular/Full port, Flanged Ends, Screwed, SW Ends Special Service Ball Valves for Cryo Application.

Class 150 / 300 / 800 Regular/Full port, Flanged Ends, Screwed, SW Ends Special Service Ball Valves for Cryo Application.

Key Features
  • Maintenance-free live-loaded double sealing stem packing ensures high cycles life and positive sealing.
  • ISO 5211 Mounting Pad Allows for mounting of actuator.
  • Blow-Out Proof Stem.

These ball valves meet test specifications as per BS 6364. Applications such as deep freezing and cooling involve cryogenic technology based on nitrogen, oxygen, and other gases.

A special type of PTFE grade ensures excellent mechanical resistance and stable torques at low temperatures. The cryogenic stem extension is provided. It is manufactured as a one-piece item with a stem for increased mechanical strength. These positions stem and stem packing away from cryogenic fluid to prevent stem seal freeze up and ensure superior performance. These ball valves can be provided with an Integral mounting pad ISO 5211 and can be used for actuation.
