A fluid-controlled valve includes a housing, a valve, and a sealing member. The housing has an annular valve seat, which has a fluid passing hole therein. The valve sits on or is separated from the valve seat to close or open the fluid passing hole respectively. The sealing member is attached on the valve. The sealing member has a sealing lip, which is closely attached to the valve seat while the fluid passing hole is closed by the valve, to seal a gap between the valve seat and the valve. The sealing member has a load receiving portion, which contacts the valve seat while the fluid passing hole is closed by the valve, in addition to the sealing lip.
