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. Jacketed ball valves as per application requirements are provided with higher size flanges.
