How to deal with the problem of stainless steel ball valve?

1, why the two-seat stainless steel ball valve will oscillate when the small opening is working?

If it is a single core, the stability of the flow-open medium ball valve is generally very good, and the stability of the flow-closed medium will be much worse. Generally, the two-seat valve will have two spool, the upper spool is open, and the lower spool is closed. Once this setting is applied to small opening work, the flow closed spool is easy to cause vibration of the valve.

2. Why can't the double sealed valve replace the cut-off valve?

The overall advantage of the two-seat valve spool is very obvious, the use of force balance structure to ensure a large pressure difference, but at the same time there are obvious shortcomings, that is, the two sealing surfaces are often not the best contact, there will be a large leak. Once it is mandatory to use in the cut off occasion, it will greatly affect the work efficiency.

3. Why is the anti-blocking performance of Angle stroke valve better than that of straight stroke regulating valve?

The used users only take, the valve spool of the straight stroke valve belongs to the vertical throttling structure, in which the medium flows directly into the horizontal flow, which will make the flow channel inside the valve chamber reverse turn, the flow path is quite complex, many dead zones cause the precipitation of the medium, and finally cause blockage. The angular stroke valve throttling is horizontal, the medium is also horizontal flow into and out, so that the dirty medium will be taken away in time, and the flow path is straight will not cause sedimentation and blockage, so the anti-blocking performance is definitely better.
