T1ST1Valve
T1S · Tier 1 Service · Valve unit
Engineering, design and industrialisation of aerospace solenoid valves — cryogenic, hydrogen and helium-pressurisation — for launchers, eVTOL and defence.
We are a unit specialised in the design and industrialisation of valves, with broad experience in home appliances, automotive (engine oil flow control, on/off and proportional valves) and aerospace (proportional adjustment of helium flow-control valves for pressurising rockets and satellites). We apply the same meticulous attention to detail to our aerospace customers and to automotive valve makers looking to diversify into this sector.
01 About us
Expert valve engineering, from home appliances to space.
We are a team specialised in solenoid valves for home appliances, automotive, railway, aeronautics, aerospace, medical devices, eVTOL, hydrogen and defense, among other sectors. We have worked for years alongside the leading companies in each sector, following the product end to end: engineering, industrialisation, quality and troubleshooting in our customers’ systems. We bring technological solutions backed by specialised laboratories and universities.
02 Key industries
The four sectors our valve offering focuses on.
Tap or click a card to flip it and see more information.
Helium pressurisation, venting, purge, fill and termination.
Helium pressurisation, termination, reaction control, purge and fill valves for launchers and satellites. Fail-safe design and single-point-failure analysis from the first sketch.
Compact, lightweight valves for the air mobility of the future.
Compact, low-mass valves for electric and hydraulic propulsion systems, held to the same reliability standards as crewed aviation.
High-pressure sealing and H₂ material compatibility.
Shut-off, proportional and purge valves for FCEV vehicles, hydrogen eVTOL and trains, with high-pressure sealing and H₂ material compatibility validated.
Reliability, intrinsic safety and single-point-failure analysis.
DFMEA, reliability index and single-point-failure analysis for safety-critical components, with full traceability through industrialisation.
03 Services
From requirement to flight: we support every stage of a valve’s life cycle.
Requirements and architecture, electromagnetic design, mechanical dynamics, sealing and simulation.
DFM, tolerance chains, standardisation and part simplification to build it right first time.
Risk analysis and DFMEA, reliability and uncertainty index, single-point-failure analysis.
A technical bridge for automotive valve makers (Spain, France, Italy) diversifying into aerospace.
We transfer engineering judgement to your team: valve architecture, sealing, reliability and qualification.
Failure investigation, incident resolution and optimisation of existing designs.
Additional service: we support automotive valve manufacturers (Spain, France, Italy) that want to diversify into aerospace, as a technical bridge into the new sector. Computational fluid/valve simulation and modelling is offered through a specialised external partner.

05 Method
06 Principles
The three axes behind every design, industrialisation and service decision.
Fewer parts, controlled tolerances and design for manufacturing from day one: same performance, lower cost and shorter lead time.
Fail-safe design, DFMEA and single-point-failure analysis. Critical valves like the Termination Solenoid Valve leave no room for surprises.
Every incident and every qualification feeds the next design: failure investigation, standardisation and lessons learned.
