A three-way solenoid valve manufactured by Aerojet General, measuring approximately 6 x 6 x 2.75, a parts tag wrapped around the upper portion reading, “Valve Solenoid 3-Way, Pt No. P/N 1133224-7, Ser. No. 0000138.” In fine condition. A valve from the AJ10-137 SPS engine that was built to power the Apollo CSM back from the moon. Nitrogen used in the engine’s Pneumatic Control System (PCS) passed through these three-way solenoid valves en route to an actuator that operated ball valves as part of the bi-propellant valve assembly; the ultimate purpose of these valves was to exercise control over the flow of fuel and oxidizer to the injector and combustion chamber of the engine.
