api 6a ball valves Description
API 6A ball valves are American Petroleum Institute (API) compliant valves designed for use in wellhead installations, production trees, and high pressure pipelines in oil and gas production. Its core standards include:
Pressure Rating: Covering 2000~20000Psi (~13.8~138MPa) high pressure scenarios;
Specification level: supporting PSL1~PSL4 (product specification level) to meet the reliability requirements of different working conditions.
Structure and design features
Main Configuration:
Connection: flange (RF/RJ) or threaded connection, suitable for wellhead device and pipeline quick installation;
Material grade: AA (carbon steel), DD (duplex stainless steel), HH (nickel-based alloy), etc. according to the corrosivity of the medium.
Performance enhancement:
Sealing technology: Hard sealing structure (e.g. tungsten carbide or metal cladding) can resist particle-containing media washout and acid corrosion;
Fire-resistant design: certified by API 6FA/6FB fire-resistant test to ensure sealing and operational performance under fire conditions.

Suggestions for selection
| Terms | Selection Points |
|---|---|
| pressure rating | Selection based on wellhead design pressure (e.g., 10,000 Psi conventional wells, 20,000 Psi ultra-deep wells) |
| Material grade | Preference for acidic media is given to HH grade (nickel-based alloys) or DD grade (duplex stainless steel). |
| Driving method | Recommended electric/hydraulic drive for high-risk areas, supports remote emergency shut-off |
