Threaded End Ball Valve
A threaded ball valve achieves opening and closing via a ball rotating around the valve body's centerline. Categorized by connection type as internally threaded or externally threaded, it includes different constructions such as two-piece and three-piece designs.

Products Description
The threaded ball valve, also known as a threaded full-bore ball valve, is a type of valve used to control liquid flow. It is widely applied in petroleum, chemical, urban water supply and drainage, pharmaceutical, and other industries. Comprising components such as the ball, stem, valve body, and seat, it achieves on/off control through rotation of the spherical closure element.
Features of Threaded Ball Valve
(1) Low flow resistance;
(2) Simple structure;
(3) Compact size and lightweight construction;
(4) Plastic sealing surfaces ensure excellent sealing performance;
(5) Easy operation with rapid open/close action, suitable for remote control;
(6) Simplified maintenance: Sealing rings are typically removable for easy replacement;
(7) When fully open or closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion by fluid flow.
Advantages of Threaded Ball Valves:
- Lowest flow resistance: Internal flow path design minimizes flow resistance (approaching zero), ensuring optimal fluid dynamics.
- Rapid open/close operation: Achieves switching in 0.05-0.1 seconds with specific designs, suitable for automated test systems requiring instantaneous response.
- Reliability in corrosive media/low-boiling liquids: Operates without jamming even without lubricants, making it dependable for aggressive fluids.
- Complete sealing integrity: Maintains leak-proof performance across extensive pressure and temperature ranges.
- Compact and lightweight construction: Space-efficient design with reduced mass, ideal for low-temperature media systems.
- Symmetric valve body: Withstands pipeline stresses and high-pressure differentials effectively
- Broad applicability: Accommodates diameters from millimeters to meters, functioning in high-vacuum to high-pressure environments.
- Simplified installation: Adapts to multiple connection methods (e.g., flanged, welded, threaded) for versatile deployment
