Small open of the two-seater pneumatic valve work, it's easy to the cause of the oscillation?

the used may find two-seater pneumatic valve, when used in small open prone to oscillation, a lot of people don't know this is what causes, so we are here to give you a brief analyse why?
actually for single core, if the media type is away, the stability of pneumatic valves are better; If the medium is flow closed type, the stability of the pneumatic valve will be less. Two-seater pneumatic valve usually have two pneumatic valve core, under the general pneumatic valve core are in a state of flow closed, pneumatic valve core will be in the state of flow to open, so when working in a small open of the two-seater pneumatic valve is easy to cause the oscillation of pneumatic valve.
that is in a small open of the two-seater pneumatic valve work easily when the analysis of the causes of oscillation, the hope can help you to understand!
