Valve assembly

A valve assembly embodiment includes first and second valve devices and a coupling mechanism. Each of the first and second valve devices may include first and second fluid paths and first and second valve members positioned at the first and second fluid paths, respectively. Both the first and second valve members may have an open position allowing fluid flow along the first and second fluid paths through the first and second valve members and a closed position preventing fluid flow along the first and second fluid paths through the first and second valve members. A coupling mechanism may be coupled to each of the first valve member and the second valve member. The coupling mechanism may be configured to transition one or both of the first valve member and the second valve member between an open position and a closed position when the valve assembly is actuated. 阀组件实施例包括第一阀设备和第二阀设备以及联接机构。第一阀设备和第二阀设备中的每一个可以包括第一流体路径和第二流体路径以及分别定位在第一流体路径和第二流体路径处的第一阀构件和第二阀构件。第一阀构件和第二阀构件两者可以具有允许流体沿着第一流体路径和第二流体路径流过第一阀构件和第二阀构件的打开位置和防止
