Valve Selection

[pumped]

I'm looking to replace a few 6" pinch valves (one manual and one automated). The material being conveyed is nickel chips (approx. 17-25mm in diameter and approx. 3-5mm thick, density of 8.9g/cc @ 300K). The rubber internals are wearing out (gravity feed piping system @ 40 degrees off of a 80T storage bin) and we need to replace them with metal. I was looking at a full port ball valve for the manual and either a knife gate/plug valve for the auto. I'd appreciate any and all comments on the suitability of these valves in this type of service. Thanks.

You might also want to talk to some of the guys who specialize in valves for solids conveying. Premier Pneumatics and Salina Vortex come to mind.
