I always knew HVAC systems were alive! Guess I can finally explain to people why I got into hvac/building tech in a cool way… thanks. In all seriousness though

I always knew HVAC systems were alive! Guess I can finally explain to people why I got into hvac/building tech in a cool way… thanks. In all seriousness though: What else does a valve come with, necessarily, for it to be a valve - some form of actuation, for without actuation, it is just an aperture or a wall. It is actuation that gives it its “valveness.” And for there to be actuation, there must be some mechanism for driving that actuation: in other words receptors/sensors. Without a sensor, it’s just a flap flailing in the noise, pure chaos. Even a simple one-way valve, diode etc has this notion of sensory reception present physically embodied in its architecture (where the signal and the modulated flow are one and the same in the case of a one way valve). All that is just to say that we can kind of think of a valve as the simplest cybernetic system, ie sensor + actuator. And on the other hand, like you suggested, we can probably boil any cybernetic system down into a network of valves in some abstract sense, things that receive flows modulate them (whether discretely or continuously, analog or digital, soft or wet or hard or dry), and route them according to other signals, etc etc
