Description
The PY4CY ball valve is specialized for cryogenic conditions. It is used for liquid nitrogen and the LNG-market. Thanks to its extended stem it can be used at a minimum temperature of -196ºC. The stem allows the valves to be used even if the pipeline is frozen. The ball valve has an upstream pressure relief hole for excessive valve cavity pressure in a closed position.
