Cartridge for faucet valve

摘要

This invention relates to a valve assembly that has a seat for the flow control seal that is contained on a sleeve-like seating assembly that sits upon a shoulder in the housing whereby the extension of the seating assembly beyond the lower end of the housing in a downward and axial direction is fixed. This construction insures that the seat for the flow control valve must be withdrawn from the faucet body with the rest of the valve assembly.
