FREE-VALVE rubber lined swing disc check valve is a type of one-way valve that can automatically prevent the backflow of media in the pipeline. Its valve disc rotates around the spindle under the action of fluid pressure to achieve opening and closing. When the inlet pressure is higher than the outlet, the valve opens and the medium flows through.

The check valve is a type of automatic valve that uses the force of the medium to open and close disc, preventing backflow of the medium. When a fluorine lining is applied to the  flow surface of the check valve, it isolates the medium from direct contact with the metal body. This type of valve is known as a fluorine-lined check valve. It automatically opens when corrosive media flow in the forward direction and closes against the flow , effectively preventing backflow.
