Abstract

A valve and valve cartridge assembly can provide an opening and closing operation with a low torque. The valve and valve cartridge assembly can be switched between a first transmission relationship and a second transmission relationship, and the first and second transmission relationships are formed between the top of the valve cartridge and a transmission device. The first transmission relationship is established so that the valve cartridge is driven to rotate axially. The second transmission relationship is established so that the transmission member drives the valve cartridge to carry out a squeeze sealing movement.
