V-shaped PFA lined electric ball valveElectric V-shaped PFA lined ball valve, V-shaped electric PFA lined ball valve, electric PFA ball valve, PFA lined electric V-shaped ball valveThe valve core adopts a V-shaped hemispherical structure, which can be exposed to ozone and sunlight for a long time without aging; A valve suitable for controlling fluids in highly corrosive working conditions such as strong acid, strong alkali, hydrochloric acid, etc. Among all plastics, the refractive index is low, allowing for a very direct observation of the flow of the medium inside the cleaning pipe; Capable of withstanding the effects of all strong acids, strong oxidants, strong reducing agents, and various organic solvents except for molten alkali metals, fluorinated media, and those above 300 ° C. Low water absorption The valve cavity and ball body of the electric V-shaped PFA lined ball valve are both made using high-pressure injection molding technology, lined with corrosion-resistant and aging resistant PFA, thus possessing reliable corrosion resistance and sealing performance. The V-shaped PFA lined ball valve core is designed with a specially shaped V-shaped notch, which has precise flow characteristics and control functions, suitable for various control occasions. It has the characteristics of compact structure, small volume, and high flow capacity. Suitable for controlling gas-liquid and solid granular media. Due to the seamless rotation between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for controlling suspensions and solid particles containing fibers or small solid particles.

It is widely used in industrial sectors such as chemical, petroleum, metallurgy, and medicine, and can adjust or cut off strong corrosive media such as acid and alkali in the production process. It has a significant effect in water treatment process control.

Main purpose:

The V-shaped ball valve core is designed with a specially shaped V-shaped notch, which has precise flow characteristics and control functions, suitable for various control occasions. It has the characteristics of compact structure, small volume, and high flow capacity. Suitable for controlling gas-liquid and solid granular media. Due to the seamless rotation between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for controlling suspensions and solid particles containing fibers or small solid particles. It can be widely used in industrial sectors such as chemical, petroleum, metallurgy, and power, to regulate or cut off strong corrosive media such as acids and alkalis in the production process.
