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 the stem for increased mechanical
strength. This positions stem and stem packing away from
cryogenic fluid to prevent stem seal freeze up and ensures
superior performance. These ball valves can be provided with
Integral mounting pad ISO 5211 and can be used for actuation.
