What is the sealing performance of large-diameter gate valves? (DN000 and above)
There are no hard-sealed knife switches that don’t expose anything; besides, with such a large diameter, factors like the temperature of the medium in use aren’t known
For steam and coke particle unloading, what is the leakage amount?
For steam, a knife switch is not needed; it can be used for discharging coke particles
Generally, knife gate valves are only used for solid materials, such as coal, coke, ash, and slag
