Fluorine lined ball valve Q41F46-16C

Ball valves use a ball core with a circular through-hole as the opening and closing element. The ball core rotates around the centerline of the valve body with the valve stem to achieve the purpose of opening and closing the valve.

The basic series of ball valves is Q41F46 type, which can be divided into two types of structures: two-piece and three piece. In addition to the small fluid resistance, fast opening and closing speed, and simple structure that ordinary ball valves have; It also has the following advantages

(1) Ball valves with FEP lining layer have extremely high chemical stability and can be used in any highly corrosive medium except for molten alkali metals and elemental fluorine;

(2) Adopting a full bore, floating ball structure, the valve can be closed without leakage within the entire pressure range, making it more convenient for ball cleaning and pipeline maintenance of the pipeline system;

(3) The ball of the opening and closing part is integrated with the valve stem casting (forging), which eliminates the possibility of valve stem impacting the pressure bearing part due to pressure changes, fundamentally ensuring the safety of use in engineering;

(4) The structure is compact and reasonable, with the smallest internal cavity 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 ensures zero leakage of the valve;

(5) The 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 sides, and can achieve online rapid replacement and maintenance.
