Content

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.The working principle of the Rubber plate swing check valve is that the medium enters from the inlet end, and the medium pressure generates an opening torque on the rocker shaft, overcoming the rocker’s gravitational torque to open the valve disc, allowing the medium to pass through. Once the medium flows back, the two torques act in the same direction on the rocker, causing it to close and prevent backflow. At this time, the medium pressure fully acts on the rocker, converting the pressure into sealing force.

Features

The disc is designed as a wholewith special
Easy to install,the valvecan be used for vertical installation.
The channel is in a flow line shapein the valve, and the flow resistance is smaller than that of the lift check valve.
The lining material is optional, which can be applied to a variety of media ,the valve has good corrosion resistance.

FRH44J EPDM NBR Viton Rubber Lined Swing Flapper Check Valve

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. T
