Meter and control propellant delivery.
Propellant feed encompasses storage isolation, pressure regulation, filtration, metering, valves, tubing and sensing. Some vendors sell complete assemblies; others supply building blocks or integrate purchased hardware. Hall gas feed is separated here from adjacent cold-gas and chemical-propulsion capabilities.
These are sourcing candidates, not a confirmed Starlink supply chain.
Supplies xenon metering assemblies and separate high-pressure mechanical regulators. These occupy different stages of the feed chain and should not share one undifferentiated pressure rating. [9][10]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers latching valves, micropneumatic regulation and satellite gas-feed components. The exact model governs compatibility, flow, pressure and whether continuous holding power is required. [11]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Supplies valves, restrictors and other compact fluid-control building blocks for space systems. An integrator must still design, assemble and qualify the complete propellant path. [12]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers xenon pressure regulation for electric propulsion as well as other spacecraft valves. The reviewed XRFS is associated with ion-engine feed, so Hall compatibility needs verification. [13][8]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers metering and tank-pressure-management components for its propulsion architecture. The flow controller and management assembly perform different jobs and have different pressure boundaries. [5][4]
Company location: United States
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers the Aurora PMA as a separate component or within its complete engine. The assembly provides anode/cathode feeding with control allocated to the matched power electronics. [3]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers feed assemblies alongside its Hall systems and describes in-house valves, accumulators, restrictors and filling hardware. A quote should distinguish components from a qualified assembly. [7][6]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers propellant management within matched Hall propulsion systems, combining in-house and commercially sourced elements. The underlying component manufacturer can differ from the system supplier. [1]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers integrated electric-propulsion scope including propellant management and regulation. Public portfolio material identifies the system function but does not establish the OEM of every internal valve. [2]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Offers cold-gas system integration and space pressure instrumentation. These are adjacent feed-chain capabilities; the reviewed sources do not establish a drop-in Hall xenon feed package. [14][15]
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
Integrates electric, chemical and cold-gas propulsion with tubing, assembly and subsystem-level engineering. This is an integration partner rather than a claim to manufacture every feed component. [16][17]
Company location: Sweden
Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Identify included isolation valves, regulator, metering, filters, sensors, tubing and redundancy.
Match the full tank blowdown curve to the regulator and downstream metering operating range.
Compare anode and cathode flow separately at stated upstream pressure and propellant.
Check wetted materials, seals, purity limits and contamination requirements for the selected gas.
Preserve test gas, pressure, temperature and leak-rate definition when comparing.
Check cycles, response time, latch behavior and holding power for the actual mission duty cycle.
Match drivers, pulse/hold currents, telemetry and PPU or spacecraft control ownership.
Include plates, tubing, heaters and supports rather than comparing bare-valve mass with assembly mass.
Request proof/leak/cleanliness records and environmental testing for the assembled feed path.
Specifications belong to the named product and configuration.
Select an upstream regulator if tank pressure exceeds this controller envelope.
Bang-bang regulation; legacy public heritage does not establish current revision or compatibility with an arbitrary Hall thruster.
Startup flow is a separate operating mode; verify its duration and branch allocation.
Manufacturer pages and technical documents support the linked claims. A review date is not a publication date or stock check.
