Eaton developed the first metal-to-metal seal pyrovalve and has since built a reputation for proven performance with this technology on launch vehicles, satellites, deep space missions and missile applications. Pyrovalves isolate combustible compounds, releasing fuel at the moment required to ensure precise navigation and landing, making them an essential component of space vehicle and satellite propulsion systems.
Our pyrovalves are recognized for their reliability, low weight, extremely low leakage, low pressure drop and successful missions completed. We offer pyrovalves in all sizes, pressure ratings, flow types, and materials with media compatible pyrovalves also available. Our engineers can customize a solution for your application-specific requirements.
