8" NSF 61 Full (80%) Port Valve MJ 1

[gibfrog]

I am looking for an 8" NSF 61, full (or 80%) port valve, like a ball or an eccentric plug valve with Mechanical Joints.

I found tons of =< 4" NSF 61 brass/bronze ball valves and tons of non NSF 61 Stainless Steel 8" ball valves.

I found one 8" eccentric plug valve

but it has an epoxy coating on a ductile iron body. I have a concern for the long term durability of the epoxy coating, one little nick & I have accelerated corrosion.

This is for a potable water line, that should be "piggable".

Any suggestions would be most welcome.

Apparently a Wedge Gate valve is the answer. Any suggestions regarding full port mid-range NSF61 wedge gate valves?
