Valve manufacture ?

[Flyone]

I have a 2012 model, and trying to verify the make of the 3" black tank drain valve. I called customer service and they said probably a Valterra (Probably ?). He said that is what they use these days. Does anyone happen to know if they used Valterra on 12 models? Going to order an electric valve actuator to replace the manual valve operator and need to know valve model to order correct operator. Going to replace the old manual pull operator which is about 10 ft. Long cable inside the split casing protector and getting very very hard to open and close. Has anyone else replace theirs with an electric valve, if so how is it working? Recomendations?

These are the manufacturers of waste valves: Valterra, Grentec, Anonda, Larden, and Bristol. Without dropping your bottom cover, it might be hard to tell what brand you have. Is there any markings on your handle???
