Outflow orifice enter in FlexTable

Hi Normand, the field that you are unable to edit in the flextable is the outflow orifice field that only applies to the other air valve types that have a single outflow orifice. When using a triple acting air valve, it does not use that field but rather uses two separate fields, one for the large outflow orifice and one for the small outflow orifice. Note the three different input fields mentioned in this article.

You will need to add those separate fields to the flextable using this information, in order to edit them in the flextable

Thanks, Just before writing my request I inputed the value in the property box and when I came back to the flextable the column was there: Diameter Large air Outflow Orifice, with the values in place.  Is that possible or did I add the column by myself while setting up the model and forgot about it?  I am 67 and on Friday's, it is starting to show...  By the way I saved your air valve article in PDF in 2018, you are an excellent technical writer, I wish I had the time to try more stuff presented in the Bentley Wiki.  Have a nice and safe fourth of July Jesse.

Hello Normand,

If you had already used option of double acting air valve and specified air inflow and air outflow orifice diameters in the element properties then that value will be visible in the flex table for triple acting air valve type as well, just that you wont be able to edit it. 

Like in below case, I haven't used double acting air valve and only specified diameter values for triple acting, then diameter (air outflow orifice) value will be shown as zero.

Hi Sushma,

Yes, in technical terms: all is ketchup!

We do a lot of air valve logging here during pump station commissioning or inquiries on sites.

They are the trickiest boundary conditions to get right.

We are starting to use vertical pipe under them in models as presented in Jesse Dringoli article presents as an option.

Have a nice and safe business week.
