Provided is a breather valve with which the degree of opening in the valve-open state can be increased while improving the valve-closing force in the valve-closed state. This breather valve (1) is provided with a switching mechanism, and when the degree of opening of a valve body (4) is equal to or greater than a prescribed value (A0) a pressure application space (S1) and a space outside a container (100) are connected. A valve-closing force in accordance with the air pressure (P1) in the pressure application space (S1) acts on the valve body (4), and when the degree of opening of the valve is equal to or greater than the prescribed value (A0) the valve-closing force decreases. Thus, the valve-closing force can be reduced and the degree of opening can be increased in a second valve-open state while improving the valve-opening force in the valve-closed state.
Provided are: a valve control device which is capable of reducing the difference between a set opening amount and the actual opening amount, when executing a partial valve stroke test; a valve control system; a method for calculating a valve control coefficient; and a valve control method.

The microcomputer 7 acquires a set opening amount of the shut-off valve 1. Furthermore, the microcomputer 7 controls the solenoid valve 5 to a value obtained by dividing the acquired set opening amount by a predetermined coefficient C.
