유압 밸브를 제어하기 위한 시스템 및 방법이 제공된다. 일 실시예는 플래퍼 어셈블리를 통해 유압 밸브의 리턴 라인용 오리피스를 차단하고, 플래퍼 어셈블리에서 형상 기억 합금(SMA)의 상 변화를 개시하며, 상 변화에 응답하여 플래퍼 어셈블리를 통해 리턴 라인용 오리피스를 개방하는 단계를 포함하는 방법이다.

    Systems and methods are provided for controlling hydraulic valves. One embodiment is a method that includes blocking an orifice for a return line of a hydraulic valve via a flapper assembly, initiating a phase change in a Shape Memory Alloy (SMA) at the flapper assembly, and opening the orifice for the return line via the flapper assembly in response to the phase change.
