ABSTRACT:
A faucet valve cartridge for a dual handle faucet which facilitates conversion between a lever-operated faucet and a knob-operated faucet utilizing identical components. The cartridge may be used to control either the hot-water supply or the cold-water supply to the faucet spout. The cartridge includes an integrally formed stop member and housing within which is rotatably disposed a valving member. The housing includes a pair of outlet ports and is open to the bottom to receive the valving member and a pair of cooperating valving plates which control fluid flow. Orientation of the valving plates within the housing controls the specific configuration of the valve cartridge. Preferably the valving plates are made of a ceramic material to reduce wear and facilitate rotation.
