Material of the spool for high-pressure needle valves

I would like to ask everyone: for the high-pressure needle valves used in steam condensate systems, the valve cores and seat surfaces suffer severe erosion, resulting in serious internal leakage. If cladding is used, what material would be suitable? And will the valve remain durable after cladding? The pressure is 150 kilograms, the medium is steam condensate, and the temperature is room temperature.

Reply to 1# shl86125: Is it possible to raise the pressure rating by one level?

This is a control valve, and it has nothing to do with the pressure rating. Just choose a high-temperature and high-pressure globe valve; it has a Stellite surfacing

What are the temperature and pressure? Use J61Y-P56170V
