Thanks for making this mod!
While I like the pipes with restricted connections and the separate line for all the pipes and pumps, I use a valve from another mod, which I consider far superior to the valves from the valve mod. Still, the 3 valves I will never use show up in the recipe list, even worse, the valve mod I use and the one you made a mandatory dependency share the same icon.
Could you consider making the valves mod an optional dependency?
As far as I can tell, the valves are not a requirement to use the functionality you provide.
Cheers and keep up the good work!
