    The ColdFlow Series cryogenic valves by Flowserve are designed with an extended bonnet to protect packing, gaskets, and seals from cryogenic temperatures, ensuring reliable sealing properties even in extreme conditions.

     

    The valves can be equipped with special gaskets and packings for operations at temperatures as low as –69 °C.

     

    Depending on the application, these valves are available with a top entry design for easy maintenance or with a simple extended bonnet attached to the valve body.
