Abstract
An object of this invention is both to prevent contamination of a fluid passing a fluid control valve and to prevent a tilt of a valve body in a moving direction and vibration of the valve body. The fluid control valve comprises a valve body that is arranged on an inner surface of a valve chest through a predetermined space in the valve chest and that is arranged on a valve seat arranged in the valve chest in a detachable manner, an actuator that biases the valve body in a direction of opening the valve, a valve body return spring that biases the valve body in a direction of closing the valve, and a tilt restraining spring that biases the valve body in a direction of resolving a tilt of the valve body to an open/close direction.
