Valve has released a handful of hardware pieces, though most were failures. There was the steam machine(s), which were just Linux pcs that valve put together as a response to windows thinking about going to an exclusive app store, the steam deck is really a continuation of that effort. Steam also had the link, which is actually a pretty good casting device to link a pc to a tv over wifi/ethernet, but the lag was a bit too much for gaming, especially without a wired connection. The steam controller was marketed alongside the link as a way to make a pc more like a console, it had some positive buzz, but never got super popular. Valve also released a vr headset called the Index back in the vr craze, but that whole market is pretty niche. TLDR. Valve has been making hardware for a while now, but it's mostly about proving there is a viable non-Microsoft market if they are forced out of Windows.
