ColdFlow Series

By using an extended bonnet, the packing, gaskets and seals are protected from cryogenic temperatures, thus ensuring their sealing properties. Optional special gaskets and packings can be used to operate at temperatures as low as – 69 °C. Depending on the application, Flowserve cryogenic valves are available with a top entry design for the easy maintenance of valves located in a cold box or with a simple extended bonnet attached to the valve body.
