Description

The PY4-CY FS ball valve is a fire safe version (according to EN ISO 10497) specialized for cryogenic conditions. When fire does break out, it is important that it does not spread through failures in pipe-work systems. Even under the most extreme conditions shut-off valves must provide a reliable sealing to the outside.

Fire Safe Test
The valve was submitted to a fire test during 30 minutes at 2 bar. During the test the average temperature of the calorimeters was found above 650°C. After the test valve was checked and reprussrised. The valve body was found tight. It is used for liquefied gases, such as the LNG-market.
