Hi,
I need advice for most suitable material for ESDV butterfly valve. Valve size is 24", pressure class 300# and valve service is condensate but it will be flushed with seawater and freshwater. Valve also will be installed on the installation in a tropical marine environment.
Is anybody have experience with galling issues in ball valves with ball and seats being hardfaced with Stellite 6?
In my case the valve is 8" CL300, op. temp -9/+65 Deg C. op. pressure limit is 48 Barg.
