Looks like the power supplies and cage for some kind of specialized rack unit (old telecom maybe). The panel on the top has a bunch of high wattage resisters on it and I would guess that part is a load testing jig for the power supply section. If you could get a better picture of the label on the card maybe able to find what it is. As for valve you would have to go with “specialized cage with burned out power supplies” and maybe even consider it a negative value for the lot because if you win you would have to dispose of it.
