ABSTRACT:
A rotatable wedge cartridge valve has a cartridge body defining a cartridge chamber of a defined internal width having flow ports in communication with the cartridge chamber. A rotatable wedge valve cartridge assembly is removeably positioned within the cartridge chamber and has a controllable width. A core member defines a flow passage and has a spherical outer surface portion. A valve seat is located within the cartridge chamber. A rotatable wedge valve member is mounted for rotation relative to the core and has a concave surface portion in rotary guided relation with the spherical outer surface. The rotatable wedge valve member also has an external convex surface that is positioned for sealing engagement with the valve seat and has a geometry developing a non-uniform wall thickness along the rotatable wedge valve member.
