A valve for an antifreezing water tab is provided to reduce maintenance cost by removing necessity of sealing member exchange and prevent leakage of the water. A valve for an antifreezing water tab includes a valve housing(210), a valve body(220), a spring(230), a fixing ring(240), an auxiliary valve(260), a first sealing(251), a second sealing(252), and a third sealing(253). The valve housing has a drain hole(211) in communication with the exterior. The valve body has a shaft part having an inner passage. The spring resiliently supports the valve body. The fixing ring is insertable into the shaft part. The auxiliary valve is mounted on an operation rod(20) to push the valve body from the fixing ring. The first sealing is disposed to be spaced apart from the drain hole. The second sealing is disposed opposite to the first sealing. The third sealing is engaged with an outer periphery of the fixing ring.
