Ferromagnetic core valve gives rapid action on minimum energy

Miniature solenoid valve controls propellant flow during tests on a coaxial plasma accelerator. It uses an advanced ferromagnetic core design which meets all the rapid-acting requirements with a minimum of input energy.

Eddy current disk valve

Quick-opening, intermittent flow valve requires a small amount of electrical energy to open and which closes by the restoring action of a rubber stop. This eddy current disk valve opens in less than 100 microseconds and takes only 10 joules of energy.
