Provided is a pneumatic valve in which a seal member; a shaft provided with a valve body capable of abutting against the seal member; and a valve-actuating pressure chamber that moves the shaft in an axial direction to actuate the valve body is provided within a valve casing. The shaft has a first member that receives pressure from the valve-actuating pressure chamber, and a second member that includes the valve body and is movable relative to the first member in the axial direction. The pneumatic valve further has a stopper that is provided in a movement path of the first member, and a disc spring that is sandwiched between the first member and the second member, has elastic energy accumulated therein in a state where the first member is in contact with the stopper, and presses the valve body against the seal member.
