Equivalent length in terms of D for L/T type ball valves
Equivalent length in terms of D for L/T type ball valves
(OP)
Does anyone know of a reference that gives equivalent lengths for pressure drop calculation for L and T type ball valves? (Those that I possess only deal with the normal breeds of valve.)
Alternatively, a logical conservative adjustment to the standard ball valve allowance for these internal shapes (which I assume will increase pressure drop) would be appreciated.
Thank you to anyone who assists with this enquiry.

They provide a Cv rating for their valves which you could convert to a resistance coefficient or equivalent length as you like. However, I would suggest you get the desired information from the manufacturer of the valve you have.
