NPS 2″ – 36″ , ASME Class 150 – 900
Our Cryogenic Top-entry ball valves are manufacturerd for extremely low temperatures and cryogenic applications, where in-line disassembly is required for trim inspection and maintenance.
Our Valves are designed with an integral bonnet extension which prevents cryogenc liquids from reaching the stem packing by enabling the liquids to boil and convert to gas.
This minimizes the energy loss along the extension and protects the valve from malfunctioning.
The structural integrety of the valve reduces any thermal deformation of internal components caused by temperature variance to a minimum, ensuring the highest level of performance for tight shut-off in the most critical applications in LNG.
