Difference between an Emag valve and X-Valve/RT/ RT Pro

[liquarius]

I recently bought an Emag valve from a friend of mine to upgrade my minimag. I was wondering what the difference is between this valve and the X-Valve, RT valve, and RT Pro valve. Any input would be appreciated. I'm just trying to get my gun in order for this season.

X-valves can take a ULT. SOME Emag valves can, others can't. RT Pro valves cannot take a ULT. Otherwise, the differences are weight (X-valve bodies are Al and Emag/RTP valves are SS) and cosmetics.
