I have come across p/t charts indicating different p/t ratings for F316 and F316L (720 psi and 600psi up to 100 F) what specification governs these ratings?
When a flange is supplied with the dual grade of 316/316L which pressure rating would apply?
Are there any p/t charts indicating p/t...
I am looking for data on an old Dresser "450" series AWWA butterfly valve. Does anyone know who may have bought out this division of Dresser? Or would anyone have any information on this valve?
Any leads would be greatly appreciated.
Thanks,
