Product Description

Cryogenic Trunnion Ball Valve

CHAODA Valves Group is specialized in manufacturing Cryogenic Trunnion Ball valve. Before finish machining, all the main components such as Body, bonnet, ball, seat ring, stem and so on should all be immersed in liquid nitrogen cooling medium. When the temperature of component reaches to -196oC,keep it for 1-2 hours and then take the components out for natural treatment until returning to ambient temperature. Then repeat this process. Cryogenic treatment should also be done to all the welded spare parts to avoid the stress and prevent potential deformation.

Ball, stem & lever are the movable components of Cryogenic Trunnion ball valve. We could know clearly the opening or closing position of cryogenic trunnion ball valve through the lever or its flat type stem head. When the lever or flat side of stem head is parallel with the axes of pipe, then the cryogenic trunnion ball valve is in its opening position; However, if the lever or the flat side of stem head is perpendicular with the axes of pipe, then the trunnion ball valve is closed. 

Cryogenic Trunnion Mounted Ball Valve

The medium in Cryogenic Trunnion ball valve may blow out the stem. And in order to avoid this accident, blow-out proof stem structure is designed. The stem assembled from underneath ensures there would be no severe leakage in the packing part when the packing, thrust bearing are damaged by fire accident or other factors.
