ASME III sub ND Buterfly 6" seat valve material
ASME III sub ND Buterfly 6" seat valve material
(OP)
Hi! I am trying to get some information on valve requirements , in this case for a 6" butterfly valve. I would like to know in what article or where y can get information about what materials are specified or not for the seat of the valve. I am readig article ND-3500 but I can't conclude if seat material is specified or simply is not considered on ASME III for butterfy valves .
The design temp is 300 °C at 10 Pa[bar(g)]
Thanks a lot !
Diego

The seat for a butterfly valve extends around the circumference of the interior of the valve at the seating area.
Are you trying to repair a 6 inch valve that has a steam cut or a failure?
