Why Are 2-piece Ball Valves And Plug Valves Considered The Same Series Of Valves?

Many 2 Piece Ball Valve users question whether fluorine-lined ball valves and plug valves belong to the same category. I can assure you that they are, and the reason is simple. Let's look at their similarities:
1. Compact and rational construction, with minimal internal space in the valve body, reduces media retention. Furthermore, a special molding process creates a high-density sealing surface, and the herringbone PTFE packing combination ensures zero leakage.
2. The valve stem and valve stem are integrally cast (forged), eliminating the possibility of the stem impacting the pressure-bearing components due to pressure fluctuations, fundamentally ensuring operational safety.
3. The full-bore, floating ball design ensures leak-free sealing across the entire pressure range, facilitating ball cleaning and pipeline maintenance.
4. The FEP-lined ball valve offers exceptional chemical stability and is compatible with all highly corrosive materials except molten alkali metals and elemental fluorine.
The basic ball valve series is Q41F46. These valves are available in two types: a two-piece and a three-piece structure. In addition to the low fluid resistance and fast opening and closing speeds common to standard ball valves, these valves also offer the advantages of low flow resistance and high speed.

5. Two-piece and three-piece constructions can adapt to a variety of piping systems and operating conditions. The three-piece ball valve allows the main valve body to be separated from the two side bodies, enabling rapid online replacement and maintenance.

Fluorine-lined ball valves and plug valves belong to the same valve category. The difference is that ball valves use a sphere with a circular through-hole as the opening and closing element. Fluorine-lined ball valves rotate with the valve stem around the centerline of the valve body to open and close the valve.
