Product Description

The function of a fluorine lined check valve (also known as a check valve) is to only allow medium to flow in one direction and prevent flow in that direction. Usually, this type of valve operates automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the valve seat is cut off by the fluid pressure and the self closing of the valve disc, which acts on the valve seat.
Working principle of fluorine lined check valve
1. Floating ball check valve: It is a new type of structure with a ball disc. The feature is that the fluorine lined floating ball moves up and down along the axis of the valve body passage, and the liquid can only flow vertically upwards. Once the liquid stops flowing vertically upwards, the floating ball automatically drops to its original position by its own weight, combined with the sealing ring inside the valve body, causing the valve to automatically close.
2. Swing check valve: Its disc rotates around the axis outside the valve seat to open and close, preventing media backflow. The shaft and valve disc are designed as a whole, with all fluorine lined shafts embedded in a special groove formed between the valve body and valve cover, providing flexible opening and closing and reliable sealing.
3. Lift check valve: The structural feature is that the fluorine lined valve disc moves vertically along the inlet and outlet axes of the valve body, and its advantage is that the sealing performance of the check valve is very good.
