Valve assembly with mechanical and electro-hydraulic control
A hydraulic valve assembly includes a main control valve having a valve body housing a valve member that is movable between a first valve position and a second valve position. The hydraulic valve assembly further includes a mechanical interface operatively coupled to the movable valve member to manually move the movable valve member between the first valve position and the second valve position and one or more electro-hydraulic actuators operatively coupled to the movable valve member to automatically move the movable valve member between the first valve position and the second valve positionin response to receiving a control signal from a controller.
一种液压阀组件，包括主控制阀，该主控制阀具有容纳阀构件的阀体，该阀构件可在第一阀位置和第二阀位置之间移动。该液压阀组件还包括机械接口和一个或多个电液致动器，该机械接口可操作地联接到该可移动阀构件上以便在该第一阀位置和该第二阀位置之间手动地移动该可移动阀构件，该一个或多个电液致动器可操作地联接到该可移动阀构件以响应于从控制器接收到控制信号而在该第一阀位置和该第二阀位置之间自动移动该可移动阀构件。
