The utility model provides an end face driving pneumatic gate valve, which belongs to the technical field of valves, and comprises a shell, a valve rod, a valve rod and a valve rod, a sliding groove is formed in the end, away from the flange opening, of the valve plate; the extending direction of the sliding groove is perpendicular to the moving direction of the valve plate. One end of the swing arm is connected with the driving end of the driving device, and the other end of the swing arm is slidably arranged in the sliding groove; the swing arm is driven by the driving device to rotate with one end as the circle center, and the valve plate is driven to move between the sealing state and the circulation state. According to the end face driving pneumatic gate valve, the swing arm is driven by the driving device to swing, so that opening and closing actions of the valve plate are achieved, the requirement for the installation space is not large, the size of the whole gate valve is reduced, and the gate valve c
