18 parts, built around the TIP122. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the NerdST/Filtration-Device repository on GitHub, at the commit this page was made from: the board is Valve-Control/Valve-Control.kicad_pcb and its schematic Valve-Control/Solenoid_Control.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask NerdST before reusing the design.
