The extension bonnet provides efficient cold insulation, minimizing heat conduction and transfer from cryogenic flow, while preventing the exposure of valve packing to cryogenic media and providing a secure seal.
Features & Benefits
Extended bonnet protects the stuffing box of the low temperature valve
Extended bonnet structure facilitates the winding of the cold-preserving material to prevent the cold energy loss of the low temperature valve
The long neck structure facilitates the quick replacement of the valve’s main part through the valve cover
