Main Propellant Valves
Compact main-flow valve architectures developed around propulsion-system interfaces and operating requirements.
Products
A focused portfolio of engineering models, development programmes, and configurable concepts for liquid and gaseous fluid systems.

Valve categories
Compact main-flow valve architectures developed around propulsion-system interfaces and operating requirements.
Isolation concepts for demanding liquid and gaseous systems, configured for the required media and duty cycle.
Fast on/off concepts for engine sequencing, purging, pressurisation, and propulsion test operations.
Application-specific architectures for regulated flow and throttling studies.
Material, seal, and thermal configurations assessed for a defined medium and operating envelope.
Tailored packaging, interfaces, actuation, materials, and performance for non-standard requirements.
Technical capability
Defined for the specific valve and validation scope
Liquid or gas materials assessed per application
Response and duty objectives shape architecture
Pressure drop considered with packaging constraints
Interfaces developed around the system envelope
Application-specific rather than one-size-fits-all
Example valve solutions
Representative studio visualizations derived from AstraValve CAD views, showing the range of valve architectures we can develop around an application.
