Q41F46 fluorine lined ball valve/Q641F46 pneumatic fluorine lined ball valve/Q941F46 electric fluorine lined ball valve
It can be divided into two types of structural types: two-piece and three piece. In addition to the low fluid resistance, fast opening and closing speed, and simple structure commonly found in ball valves, it also has the following advantages:
1. Ball valves with FEP lining layer have extremely high chemical stability and can be used for any strong corrosive properties except for "molten alkali metals and elemental fluorine";
2. Adopting a full bore and floating ball structure, the valve can be closed without leakage throughout the entire pressure range, which is more convenient for ball cleaning and pipeline maintenance of the pipeline system;
3. The spherical opening and closing components are integrated with the valve stem through casting (forging), eliminating the possibility of the valve stem impacting the pressure bearing components due to pressure changes, fundamentally ensuring the safety of use in engineering;
4. The structure is compact and reasonable, with the smallest internal space of the valve body, reducing medium retention. In addition, the special molding process ensures good density of the sealing surface, and the combination of herringbone ring PTFE packing enables the valve to achieve zero leakage;
5. Two piece and three piece structures can adapt to various pipeline systems and working conditions with different requirements. Among them, the three piece ball valve allows the main valve body to be separated from the two side bodies, and can achieve online quick replacement and maintenance.
