This invention belongs to the field of pneumatic control valve technology, specifically providing a pneumatic shut-off valve. The invention aims to solve the problem of excessive noise during operation of existing pneumatic shut-off valves. To this end, the pneumatic shut-off valve of this invention includes a valve body assembly, a valve core assembly, and a sealing ring. This invention defines a distal variable volume cavity and a proximal variable volume cavity located on opposite sides of the axial direction of the movable yoke by having the valve core assembly and the valve body assembly jointly define such cavities.
