Stainless steel 3 way mixing / diverting valve? 1

[G2daG]

I've been searching for a 3 way mixing valve, electrically actuated, in the 3" to 4" range (Cv ~200). The application is not actually HVAC but so far all the valves I've found are for HVAC, so I thought I'd see if anyone here can help me.

I've found several valves from Belimo, Siemens, and others that fit the bill except for the wetted materials. We can only have 304/316, Viton, Teflon, and maybe a handful of other materials. Brass and Iron are definitely out.

Has anyone run across an all-stainless, 3 way mixing valve?

Thanks in advance!

These valves are fairly common in sanitary piping designs.
Google "sanitary mixing valves".

Thanks Compositepro - I haven't found the perfect valve yet but I think that put me on the right track.

There are plenty of industrial valves that can be fitted with rotork or similar electric linear actuators. Trim options abound - linked has a full 316 trim in your size range. I probably wouldn't spec a belimo into an industrial setting.
