A compressor assembly may include a compressor case disposed about an axis. A bleed valve may be disposed about the compressor case to translate axially and/or rotationally relative to the compressor case. A first seal may be disposed in a forward seal housing of the bleed valve a first radial distance from the axis. A first sealing wall may be fixed relative to the compressor case and configured to engage the first seal. A second seal may be disposed in an aft seal housing of the bleed valve at a second radial distance from the axis. The first radial distance may be substantially equal to the second radial distance. A second sealing wall may be fixed relative to the compressor case and configured to engage the second seal.
