rubber lined swing check valve

FREE-VALVE rubber lined  plate swing check valve has low flow resistance, low pressure drop, is easy to open, has a simple structure, and strong adaptability (such as pressure fluctuations and media contamination), thus it is widely used in industries such as petroleum, chemical, water supply, and food.

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.

FREE VALVE FRH44J EPDM NBR Viton Rubber Lined Swing Flapper Check Valve relies on the flow of the medium itself automatically opens and closes the valve disc,which is an automatic valve used to prevent the reverse flow of the medium.

FREE VALVE FRH44J Flange End Rubber Fluorine Polymer Lined Swing Check Valve relies on the flow of the medium itself automatically opens and closes the valve disc,which is an automatic valve used to prevent the reverse flow of the medium.

FREE-VALVE rubber lined swing check valves are designed to prevent the reverse flow of medium automatically,the valve disc automatically opens under the action of fluid pressure, and the medium flows from the inlet port to the outlet port
