First, the electric low temperature ball valve DQ941F Features
 1, electric low temperature valve for the use of temperature less than -100 ℃ for all valve parts in accordance with the relevant provisions of cryogenic treatment to prevent low temperature brittle material and low temperature caused by the phase change of material volume changes 
 2, electric Low-temperature ball valve with a long neck structure, the filler working temperature above 0 ℃, effectively prevent the filler due to the working temperature is too low, resulting in reduced sealing performance or seal failure, while convenient for the valve wrap insulation materials to prevent loss of cold energy 
 3, for the floating Electric low-temperature ball valve adopts imported relief pressure outlet seal design, which effectively prevents the abnormal pressure in the cavity caused by temperature change to ensure the safe operation of valves and pipelines. 
 4, The electric low-temperature ball valve adopts double stem packing and pressure butterfly Shrapnel device
