In addition, the valve may include a diverter and seal assembly that are disposed in the valve body. The seal assembly includes first and second seal subassemblies. The first subassembly has first through openings that are axially aligned with the diverter through openings. The second subassembly is axially stacked with the first subassembly and includes second through openings that are axially aligned with valve body subchambers associated with the ports. A first static seal is disposed between the diverter and the first subassembly, a second static seal is disposed between the valve body and the second subassembly, and a dynamic seal is disposed between the first subassembly and the second subassembly.
