FQ41F46 Lined Fluorine Discharge Ball Valve
I. Introduction:
The FQ41F46 fluorine-lined discharge ball valve uses a sphere with a circular through-hole as the opening and closing part. The sphere rotates around the center line of the valve body along with the valve stem to achieve the opening and closing of the valve. Adopting special molding process, the sealing surface is dense and well-formed. Combined with V-shaped PTFE packing, the valve achieves zero leakage. The sphere and valve stem are cast as one piece, eliminating the possibility of the valve stem rushing out of the pressure-bearing part due to pressure changes, fundamentally ensuring the safety during use. With all-plastic lining process, it is resistant to strong corrosion of the medium. It is suitable for pipelines of aqua regia, sulfuric acid, hydrochloric acid, various organic acids, strong acids, strong oxidants at various concentrations within the temperature range of -50℃ to 150℃. FEP is also applicable to pipelines of strong alkali, organic solvents and other corrosive gas and liquid media at various concentrations.
II. Structural Features:
1. Small fluid resistance. The inner wall of the lined ball valve is smooth, and the unobstructed flow path makes it one of the valve types with the smallest fluid resistance.
2. Quick and convenient switching. Only by rotating the sphere 90 degrees can the opening and closing actions be completed.
3. Adopting special molding process, the lining material is lined on the inner wall of the valve body, which can resist the corrosion of strong acid and strong alkali media. The lined sphere surface combined with PTFE valve seat ensures good sealing performance and achieves zero leakage.
4. It can be equipped with various driving devices such as pneumatic, electric and hydraulic devices to realize remote control and automatic operation.
5. The sphere and valve stem are integrated, eliminating the rotation angle difference and preventing the danger of the valve stem rushing out of the body due to pressure changes, ensuring the safety and reliability of use.
