Confirm the mating flange and piping details for the selected installation.
What should I check before replacing a double-flanged valve with this bare-shaft model?
Send the pipeline flange drilling and facing, nominal size, face-to-face dimension and available operating space.

Request approval of the complete replacement arrangement rather than assuming the existing drive will fit.
