Custom High-Pressure Regulators for Aerospace, UAVs & Space Applications
MEYER designs and manufactures lightweight, custom high-pressure regulators for hydrogen fuel-cell UAVs, CubeSat propulsion modules, and orbital launch vehicles. Where stock regulators fall short on mass, inlet pressure, or interface compatibility, we engineer to spec.

Custom regulator development
Off-the-shelf regulators rarely fit aerospace and space-grade missions. We design custom regulators to your inlet, outlet, mass, envelope, and qualification requirements:
- Inlet pressures: up to 700 bar
- Outlet ranges: 0–10 bar standard, custom on request
- Materials: 316 SS, hydrogen-compatible alloys, materials qualified to avoid hydrogen embrittlement
- Configurations: single-stage, two-stage, dual-output, manifold-integrated
- Interfaces: M-thread, NPT, AN, custom flange, bring your spec
- Qualification: hydrostatic, burst, leak, cycle, vibration as required by your program
Lead time
- Working prototype: 3–5 months from spec freeze
- Qualified flight unit: per program requirements
- Production batch: on request

Where MEYER regulators fit
MEYER builds high-pressure regulators for two primary use cases: fuel-cell hydrogen mobility (the HDRX-R450 family, 450 bar inlet, 0–10 bar outlet) and aerospace propellant feed (custom designs up to 700 bar inlet, configurable outlet). Both are engineered for hydrogen-compatible service with 316 SS bodies and elastomers selected for the gas in service. Configurable single- or two-stage regulation lets the design match the application’s thrust precision requirement: single-stage for cost-led mobility, two-stage where outlet pressure must remain stable across full blowdown.
Configurable parameters
- Inlet pressure: 200, 350, 450, 500, 700 bar
- Outlet range: 0–1, 0–5, 0–10 bar (or fixed setpoint)
- Stages: single (lower mass, lower cost) or two-stage (tight outlet stability)
- Body: 316 SS standard; custom alloys (titanium, Inconel) on request
- Gas service: H2, He, N2, O2 (with cleaning to ASTM G93), Xe, Ar
- Connections: M-thread, AN, VCR, custom flange
Lead time
Functional regulator prototypes from spec freeze: 3–5 months. Qualification testing and flight-unit production scheduled to programme requirements. For programs targeting first integration in under 4 months, start with a HDRX-R450 catalogue unit configured to your fitting and gas service.
