The series grooved check valve is a one-way check valve. When the medium is flowing forward, the valve flap is opened under the pressure of the fluid; when the medium flows in the reverse direction, the valve flap is closed under the spring force and the reverse fluid pressure. Cut the channel to prevent backflow.
