Calculation of air consumption for pneumatic valves
Thread Content
It was posted in the wrong place before; now I’m seeking advice from experts. We plan to install 40 pneumatic cut-off valves of DN65 size, and 8 pneumatic control valves of DN50 size. These valves need to be operated once every 20 minutes. We need to estimate the gas consumption per hour and determine what capacity gas station is required. I hope the expert can provide a more detailed response; thank you! ! !
This depends on the calculation using the effective area of your actuator
We haven’t purchased the valves and actuators yet; can’t we estimate it in advance? ? ?
Without parameters such as valve structure and pressure rating, it’s impossible to select the actuator.
Do these have to be determined after the valves are purchased? Pipe pressure is 0.4 MPa; the main media are water and steam
Provide the process parameters to the valve manufacturer; once they have selected the appropriate valve, they will be able to tell you the gas consumption.
Estimation is carried out in accordance with the standard HG/T20510-2014.
So, first buy the valves, and then design the gas flow rate :)
I have downloaded this specification, but it doesn’t provide a way to estimate the gas consumption of the shut-off valve; I would appreciate some guidance.
