Apollo Command Module Cabin Temperature Control Valve unit manufactured by Airesearch, measuring approximately 6 x 4 x 3, bearing an affixed parts label reading, “Valve Elec Mechan Rotary, Part 850028-2-2, Serial 125-117, Order NAS-9-150, NASA 004000125117.” In fine condition. Part of the Apollo Command Module (Block II) Environmental Control System, this manually controlled, motor operated valve provided the crew with a backup mode of spacecraft cabin temperature control as an alternative to failure of the main temperature control system. The valve regulated flow of water-glycol to a heat exchanger and was installed in the left hand forward equipment bay, panel number 303 (LHFEB-303).
