HOOVER ISOLATION LATCH VALVE
Secure your pressure vessels
The Hoover Tank Passivation Latch Valve is a high-reliability fluidic component designed to ensure safe and controlled isolation or venting of spacecraft propulsion systems during launch and at end of life.
Featuring a robust latching mechanism, it provides leak-tight sealing and secure actuation without the need for continuous power, making it particularly suited for critical phases such as launch isolation, controlled depressurization, and autonomous passivation.
Its compact, lightweight design and standard mechanical interface enable seamless integration into a wide variety of spacecraft platforms. Built to withstand harsh launch and in-orbit environments, the Hoover valve delivers exceptional resistance to vibration, thermal cycling, and contamination.
In line with Ascend Beyond Space’s commitment to safe and sustainable space operations, the Hoover valve plays a key role in ensuring full system demisability and compliance with the latest orbital debris mitigation requirements. Its simplicity, reliability, and performance make it an essential component for modern, responsible mission architectures.
