Q: Why do the stem and the valve use movable connections?: Stem and disc material is different, can not be made as a whole. Second, it may also be related to the way it is installed.

Q: I heard that there is a special production valve stem equipment, automation, production accuracy and production efficiency are high equipment: Horizontal lathe, stem processing accuracy is not high, the general machine tool on the line

Q: What's the difference? Will it break? If the technology is good, will it be broken with the stem? I haven't opened the valve yet. Can I catch it in the daytime with the string hook? I used the bells!! Ask God for us!!: Please go to the emblem look at the "Fisherman" post, hitting professional fish paste beans Dad I do not rob the Shu business haha!

Q: Hydraulic excavator main control valve stem wear can be changed? Will the valve bore not be worn?: It is recommended to change the set because the rod is worn out and the valve body should be worn almost as well. Change the set for safety. One is to reduce environmental pollution, the valve core and valve sleeve wear off, the gap is also large, began to leak oil.

Q: How about valve stem with 660?: If the action is not very frequent, the condition is not very complex, harsh, it should still be possible. Heat treatment will be better

Q: What is the seal between the valve stem and the valve cover?: Most valves:The seal between the valve and valve cover depends on the valve cover gasket.The seal between the valve and the stem depends on the packing.There are also valves, valves and stem seal between bellows, "O" ring, and so on.

Q: What is the difference between them in use?: It is generally divided into the upper shaft and the lower shaft. In the assembly process than the single axis slightly harder, if you want to further understand, can add my QQ 51737440, 5, I have here electronic chart, can further understanding.

Q: What is the reason that the valve stem can not be rotated in the water supply pipe?: Crown valve pressIs it stuck? You can't drive it?Or handwheel, stem does not turn?Shut off for too long too much death will not open in the first.

Q: What is the cause of valve stem vibration in electric single seat control valves?: 3, liquid medium through the valve, resulting in cavitation caused by shocks, higher frequency, usually accompanied by valve howling. High temperature large pressure difference, the use of single seat valve is relatively easy to happen, this is the control valve (valve body structure) type selection caused by improper,4, the valve core resonant frequency and pipe and fluid frequency consistent with the vibration caused by higher frequency, usually accompanied by pipe vibration. Change the valve at both ends of the process, valve opening may be eliminated.

Q: Hydraulic manifold valve, stem movement is a positive cover, what is the role?: The spool is covered, in the middle, P mouth is closedThe manifold valves do not work together at the same time. T
