API Good Quality 6D Ball Valve
**API 6D Ball Valve Specifications**
**Model No.:** API 6D
**HS Code:** 8481804090
A ball valve uses a spherical disc with a circular hole as the closing element. The ball rotates around the centerline of the valve body via the stem, allowing for quick opening and closing of the valve.
### I. Types of Ball Valves
Ball valves are available in two main structures: split body and three-piece body. These designs offer advantages such as low fluid resistance, fast operation, and a simple structure. Key features include:
1. **FEP-Lined Ball Valves:** These provide high chemical stability and can be used with most corrosive media, except molten alkali metals and fluorene.
2. **Full Bore, Floating Ball Design:** This ensures full pressure capability without leakage, making it ideal for pipeline pigging and maintenance.
3. **Compact Structure:** The reduced valve cavity minimizes medium retention. Advanced molding techniques ensure excellent sealing performance, combined with PTFE packing for leak-free operation.
4. **Split Body & Three-Piece Body Designs:** These are suitable for various pipeline systems. The three-piece body allows the main valve body to be separated from the two side bodies, enabling quick on-site replacement and maintenance.
### II. Design Standards
Compliant with GB 12237, API 608, and API 6D standards.
### III. Actuation Methods
Available in manual, worm gear, pneumatic, and hydraulic options.
### IV. Technical Parameters
- **Working Pressure:** CLASS 100 to CLASS 4500
- **Nominal Bore Diameter:** 1/2" to 46"
- **Temperature Class:** -46°C to 121°C (LU)
- **Product Specification Level:** 1 to 4
- **Performance Requirement:** PR1 to PR2
- **Material Class:** AA to HH
- **Working Medium:** Oil, natural gas, mud, and gas containing Hâ‚‚S and COâ‚‚
This ball valve is designed for reliable performance in harsh environments, offering flexibility in application and ease of maintenance. It is widely used in oil and gas, petrochemical, and industrial pipelines where durability and safety are critical.
