NASA Introduces an All-Electric Advanced Magnetostrictive Regulator and Valve
Combining MS-based sensors with a newly designed MS-based valve, NASA innovators developed a combination regulator and valve that eliminates seal friction, leakage and wear issues that often hinder typical valves. The innovation delivers rapid response times and features lightweight, compact, and highly precise components that can operate over a wide range of temperatures and pressures.
NASA’s innovation offers many advantages over typical valves. It uses a small-scale valve in a large pressure plate, which enables multiple flow paths in a single flow duct, preventing contaminants from clogging the entire valve element and lowering costs by reducing the number of valves used in a typical regulated pressure system. NASA’s approach also uses fewer moving parts than typical valves, offering greater reliability, safety and longer life. The technology reacts to transients in supply pressure dramatically faster than current methods.
The Advanced Magnetostrictive Regulator and Valve is very useful for aerospace applications, and can also be applied to:
- Aircraft engines
- Automotive fuel systems
- Manufacturing and processing
- Biomedical device implants and drug metering systems
