Estimation of the on/off time for pneumatic valves
Thread Content
It is known that the cylinder volume of the actuator for the pneumatic ball valve is 960 L, the cylinder interface size is NPT2\", the flow rate of the pneumatic control valve is 24,000 L/min, and the flow rate of the pressure reducing filter is 28,800 L/min. If it is required to start within 8 seconds, can this time requirement be met?

Gas source pressure: 0.4 MPa, one port on the cylinder.
What is the diameter of the hole through which the pneumatic control valve connects to the cylinder? If it is less than or equal to the diameter of the cylinder intake, it can be satisfied within 8 seconds.
Based on calculations + estimates of the structural dimensions not mentioned by the original poster~~~~ it should meet the 8S requirements.

What manufacturing process is used for such a large actuator?
Specifically, how is 18s estimated?
How was it determined that 8s was met? I don’t quite understand
The CV value for the 2\" fitting is estimated and depends on other components in the gas circuit. Estimated at CV=50
