When using a valve, the valve stem is not flexible. Solution: Sansheng Trap Time: 2019-11-05 Clicks:
What should I do when I encounter the inflexible or stuck valve stem when using the valve?
The valve stem is an important part of the valve. It is used for transmission. It is connected to the actuator or the handle. The valve core is directly driven to move or rotate below to realize the valve opening or adjusting function. In the process of valve opening and closing, not only moving parts, force parts, but also seals. At the same time, it is subject to the impact and corrosion of the medium, and also causes friction with the filler. Therefore, when selecting the material of the valve stem, it must be ensured that it has sufficient strength, good impact toughness and abrasion resistance at the specified temperature.
Then the factors that cause the above are:
Insufficient clearance between valve stem and bushing
The packing is out of specification when stuffing into the stuffing box. Recommended products: Electric butterfly valve-Denso actuator
Stem and stem bushing are made of the same material or the material is not selected properly
Valve stem bent
