NASA Goddard Space Flight Center has developed the NOVA zero-leak, permanent isolation valve that helps prevent leaks in space propulsion systems with operating pressures less than or equal to 500 psia. The actuator is made from nitinol, a heat-activated, non-explosive, shape memory alloy and the result is a valve that is much safer than the currently used pyrovalve.
