Abstract
A self-shut valve for a faucet may include a valve body, a valve base, a control shaft and a top cap. The control shaft includes a sealing portion that comprises a ducting pipe and a slot which can prevent the space between the valve base and the control shaft from entering into a vacuum state to enable the control shaft to return to its initial position precisely.
