Fluorine lined check valve is the direction of development for check valves

Fluorine lined valves, also known as polytetrafluoroethylene valves, are made by molding or embedding polytetrafluoroethylene resin on the inner wall of steel or iron valve pressure parts or the outer surface of valve internals, and using its superior anti-corrosion medium to make various valves and pressure vessels. But check valve The function of this type of valve is to only allow fluid medium to flow in one direction and prevent it from flowing in the opposite direction. This type of valve does not require control and generally works automatically. The working principle is that the valve disc opens under the pressure of fluid flowing in one direction; If the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc will act on the valve seat, cutting off the fluid flow and preventing the medium from flowing in the opposite direction.
In the past, traditional check valves were made of metal materials because metal has high strength and relatively stable performance. However, the price of metal is relatively high, and metal is easily corroded, which affects the performance of the valve. The emergence of plastic has solved this problem. Plastic is a solid material processed from synthetic resin or natural resin with various additives at a certain temperature and pressure. Compared to metal, plastic has a lower cost and is artificially synthesized with a wide range of materials. In addition, plastic has stable chemical properties and will not corrode, which will affect the performance of check valves. Therefore, fluorine lined check valves are the future development direction of check valves.
