A valve (100) includes a valve body (300), a spool assembly (600), and a pendulum assembly (700). The valve body (300) is adapted for fixed attachment to a mounting surface (260) having an orientation corresponding to the incline of a supporting surface (210. The spool assembly (600) comprises a spool (610) pivotally mounted within the valve body (300), and the pendulum assembly (700) pivots the spool (610) in gravitational response to the orientation of the valve body (300). The valve body (300), the spool assembly (600), and/or the pendulum assembly (700) include one or more elements for adjusting flow symmetry between the LIO flowpaths and the GIO flowpaths.
