Does anyone out there happen to have any old Texsteam relief valve catalogs? I'm looking for gas sizing coefficients for 7700 and 77000/87000 series relief valves.
I tried the Texsteam and NASVI routes without any luck.
I may have some info on Texsteam at my office.
I will look for it and send you anything I find.
Vapor Boilers used to use them. They are in Chicago. They might have something, but I don't know for sure.
