Tightness test method of pneumatic exhaust butterfly valve How to connect the limit line? The linear flow characteristic curve shows that the flow is proportional to the valve travel. This proportional relationship provides a constant slope characteristic, so at a constant pressure drop, the valve gain is the same at all flows. (The valve gain is the proportion of the valve core position increment. The gain is a function of the valve diameter and configuration, system operating conditions, and valve core characteristics.) Linear valve cores are usually specified for liquid level control and some flow control occasions requiring constant gain.
、 When the manufacturer of pneumatic butterfly valve can deal with these matters very well, it will certainly lay a good foundation for us to move from the domestic market to the international market. I believe that this is also the proof of our competition in the international market. Therefore, in the process of development, we must be able to deal with these aspects very well.
