Product Description

Cryogenic Welded Type PN40 DN25 to DN200 Ball Valves Pneumatic SS304

Product Description

Pneumatic low temperature ball valve refers to a ball valve with a medium temperature of +80 ℃ ~ -196 ℃, which is used for the management system of low temperature and cryogenic medium.The valve undergoes a special low temperature treatment to ensure the low temperature performance of the material. When running in low temperature conditions, it will not cause leakage due to deformation caused by temperature changes. The imported pneumatic low temperature ball valve bonnet adopts a long neck structure. Its purpose is to protect the function of the stuffing box, so that the stuffing box is located far from the low temperature, and the sealing effect of the packing is guaranteed. The neck length of the long neck can be selected according to the use temperature and the thickness of the cold insulation material.
