1-Piece Threaded Ball Valve
- 1-Piece Body, No Leakage: The valve body is cast or forged as a single piece, eliminating external body joint leak paths for high reliability.
- Compact & Cost-Effective: As the simplest and most compact type of ball valve, it offers excellent value for money.
- Low Flow Resistance: Features a full-bore design for minimal flow resistance.
- Simple Operation: A 90-degree turn is all that is needed to fully open or close the valve.
- Threaded Connection: Suitable for quick installation in various small-bore pipelines.
The 1-Piece Threaded Ball Valve is the simplest type of ball valve, featuring a body constructed from a single, solid piece of material, with the ball cavity and flow paths machined within, and threaded connections at both ends. This integral structure eliminates potential leakage from body joints, making it exceptionally robust and durable. Due to its simple design and cost-effectiveness, the 1-piece ball valve is one of the most common shut-off valves for general-purpose media such as water, air, and oil. It is important to note, however, that its one-piece construction means internal parts cannot be serviced in-line; replacement of the entire valve is typically required in case of failure.
