Stainless steel gate valve shaft packing requirements: 1, valve packing should also withstand frequent opening and closing, the sealing effect of the permanent; 2, in view of the above requirements, valve shaft packing for life or do not change for more than 10 years; 3, If the packing needs to be replaced, the design of the pneumatic valve should consider the measures that can be replaced under the condition of water pressure; 4, due to the network of soft seal gate valve, usually not frequently open and close, requiring filler inactivity within a few years, the filler is not aging, long-term sealing effect. The three-dimensional cup cover design increases the internal space, and the filtration efficiency of non-oily particulate matter can reach more than 95%.
