How to determine the maximum closing pressure difference of ON-OFF valve: Q
The maximum closing pressure difference of the ON-OFF valve is an important parameter used to determine the specifications of the cylinder. In design, the maximum working pressure of the pipeline where the valve is located is generally used (this maximum pressure is generally also the design pressure of the pipeline). If your process settings can ensure that it is lower than a certain value under any circumstances, it can also be used.
But I found a datasheet that the closing pressure differential is higher than the design pressure, will this happen?
It’s hard to say without knowing the specific process conditions. But based on my experience, it's unlikely. If this is the case, the pipe or pipe attachment may have failed.
