Membrane valve, branching outlets

One round chamber covered by a flexible sheet, with an air line above it. Air pressure presses the sheet down onto the chamber floor and closes it. This version feeds several outlets, which leave the chamber wall directly and fan out to points around a ring.

What it is for. Splitting one liquid supply into several destinations, or shutting all of them at once with a single air line.

Variants

Sizes below are given in px: units of the design grid these parts were drawn on, where one unit is 0.0076 mm. That is not the printer's pixel. The printer has its own, different pixel size, and nothing on this page is expressed in it — see Hardware and process.
