    • A valve assembly comprises: a valve housing comprising an interior cavity having upstream side and a downstream side; and a valve member movable within the valve housing between a closed position in which flow between the upstream side and the downstream side is prevented or substantially prevented and one or more open positions in which flow between the upstream side and the downstream side is enabled. The valve assembly further comprises: a sensor mounting flange on an exterior surface of the valve housing; a first bore in the valve housing linking the upstream side of the valve housing and the sensor mounting flange; and a second bore in the valve housing linking the downstream side of the valve housing and the sensor mounting flange; such that a sensor configured to measure a differential between the upstream side and the downstream side is mountable directly on the valve assembly.
    • 阀组件包括:阀壳体,其包括具有上游侧和下游侧的内腔; 以及阀构件,所述阀构件在所述阀壳体内在防止或基本防止所述上游侧和所述下游侧之间的流动的关闭位置和能够在所述上游侧和所述下游侧之间流动的一个或多个打开位置之间移动。 阀组件还包括:在阀壳体的外表面上的传感器安装凸缘; 在阀壳体中的第一孔连接阀壳体的上游侧和传感器安装凸缘; 以及所述阀壳体中的连接所述阀壳体的所述下游侧和所述传感器安装凸缘的第二孔; 使得构造成测量上游侧与下游侧之间的差的传感器可直接安装在阀组件上。
