Recommendation for valve material
Recommendation for valve material
(OP)
I'm looking for a material recommendation on a ball/seat combination to use for a ball valve.
The valve cycles 1 time in 1 second, every 30 seconds. Pressure is 1500psi, temperature at 450F, medium is Nitrogen.
We tested the valve using a carbide coated ball with a nickel aluminum bronze seat and valve lasted only 2 days. The nickel aluminum bronze showed heavy wear/galling on the seat.
