    • A latching valve (100) is provided. The latching valve (100) comprises a valve seal (102) movable between a first position and a second position to selectively open a fluid communication path between a fluid inlet port (330) and a fluid outlet port (331). The latching valve (100) also includes a first pilot valve seal (104a) movable between a first position and a second position. The first pilot valve seal (104a) selectively provides a pressurized fluid to a pilot control chamber (332), wherein pressurized fluid within the pilot control chamber (332) biases the valve seal (102) towards the first position. The latching valve (100) also includes a second pilot valve seal (104b) movable between a first position and a second position. The second pilot valve seal (104b) selectively exhausts the pressurized fluid in the pilot control chamber (332). The latching valve (100) also includes one or more shape memory alloy elements (106a, 106b) to actuate one or more of the first and second pilot valve seals (104a, 104b) between the first and second positions upon heating above a transformation temperature.
    • 提供了一种闭锁阀(100)。 闭锁阀(100)包括可在第一位置和第二位置之间移动的阀密封件(102),以选择性地打开流体入口端口(330)和流体出口端口(331)之间的流体连通路径。 闭锁阀(100)还包括可在第一位置和第二位置之间移动的第一先导阀密封件(104a)。 第一先导阀密封件(104a)选择性地向先导控制室(332)提供加压流体,其中先导控制室(332)内的加压流体朝向第一位置偏压阀密封件(102)。 闭锁阀(100)还包括可在第一位置和第二位置之间移动的第二先导阀密封件(104b)。 第二先导阀密封件(104b)选择性地排出先导控制室(332)中的加压流体。 闭锁阀(100)还包括一个或多个形状记忆合金元件(106a,106b),以在加热高于相变温度时致动第一和第二位置之间的第一和第二先导阀密封件(104a,104b)中的一个或多个 。
