APOLLO COMMAND MODULE HELIUM PRESSURE REGULATOR
USED IN THE REACTION CONTROL SYSTEM (RCS)
RCS Helium Pressure Regulator Unit, 6½" wide by 5" tall, primary regulator vent with label reading "FAIRCHILD HILLER CORPORATION. STRATOS-WERSTERN. MANHATTAN BEACH, CALIFORNIA. PN 63-036-08. SERIAL NO. 03825M940569. MFD MO 1 YR 70, U.S. SWB 9," label with 1 inspection stamp, additional yellow label reading "RUBBER CURE DATE 1Q70," secondary regulator vent with label reading "REGULATOR UNIT, PRESSURE, HELIUM, RCS. NAA/S&ID NO. CONTRACT NO. NAS9-150. NAA/S&ID INSP. SERIAL NO. SWB 9, ANA 401," each vent port surrounded by yellow label reading "VENT PORT DO NOT PLUG," base of primary regulator labelled "VHT #1 SWB 27" "VHT #2 SWB 27," base of secondary regulator labelled "IPNA 678. 63-1073-1F. SWB18. CN 1565. 63-036-08 S. S3," base of each regulator stamped "63752 H. SWB 37."
A critical piece of hardware. Each helium pressure regulator assembly consists of two individual pressure regulators connected in series. A flow limiter at the outlet of the main stage valve of the secondary unit restricts maximum flow through the regulator assembly, so that the propellant tanks are protected if the regulator fails open. This unit is a test unit, identical to that which was used on manned Apollo flights.
