Human access to space continues to evolve beyond the International Space Station, with new missions to the Moon, NASA’s Lunar Gateway, and commercial space stations. Whenever humans are involved, environmental control and life support systems (ECLSS) must be in place to maintain a habitable breathing atmosphere and thermal environment. Moog has been producing hardware in support of NASA’s Orion Crew Module, specifically used in the cabin pressurization system and thermal control system. This hardware leverages Moog’s capabilities developing space-qualified valves to control gas and liquid media. Hardware covers the gas supply and distribution systems, along with the thermal control system.

Products include high pressure (4,500 psi) oxygen isolation valves, intermediate pressure (145 psi) oxygen control valves, and low pressure (14.5 psi) cabin atmosphere control valves. Moog also provides valves for the environmental control system, including ammonia, propylene glycol, and urine isolation valves.

Moog has been successful winning work in support of NASA’s Lunar Gateway and is developing numerous ECLSS components including manually operated tank valves, pressure regulators, high pressure quick disconnects, and both high and low pressure isolation valves.

Moog’s capabilities extend beyond components to delivering system-level solutions, combining components with structures, plumbing, and electrical control to deliver an integrated and fully tested package that is able to be installed into the space vehicle system/
