Your Leading API 6A Valve Manufacturer in China
JiangHeng API 6A valves are engineered for the most demanding upstream oil and gas applications. Built to withstand extreme pressures and harsh wellhead environments, they are widely used in onshore and offshore drilling, Christmas trees, and manifold systems. After years of dedicated research and strict quality control, JiangHeng has successfully developed a full range of API 6A gate valves, choke valves, check valves, and mud valves.
For highly corrosive sour service conditions, our API 6A valves feature advanced metal-to-metal sealing and strict material selection complying with NACE MR0175 / ISO 15156 standards. This ensures absolute containment and effectively prevents sulfide stress cracking (SSC) in toxic H₂S environments.
According to your specific wellhead requirements, JiangHeng can customize valves with specialized trim materials, PSL (Product Specification Level) 1-4 ratings, PR (Performance Requirement) 1-2 testing, end connections, and various actuation methods.
Whether you are equipping a standard onshore wellhead or a critical high-pressure offshore platform, JiangHeng is your trusted partner. We offer competitive pricing while uncompromisingly guaranteeing safety and API-certified quality.
Extreme High-Pressure Reliability
- Absolute Zero Leakage: Featuring precision-machined metal-to-metal sealing (gate-to-seat and body-to-bonnet), our valves eliminate leakage paths to ensure 100% containment under extreme wellhead pressures (up to 15,000 psi or higher).
- Rugged Sour Service Design: Manufactured in strict accordance with NACE MR0175 standards, our materials undergo rigorous heat treatment and hardness testing to resist sulfide stress cracking (SSC), extending operational life in highly corrosive H₂S environments.
Strict 6A Compliance
- Precision Manufacturing: Utilizing advanced CNC machining and strict dimensional control, our API 6A valves guarantee smooth operation and minimized operating torque, ensuring reliable control even under maximum working differential pressure.
- Rigorous Performance Testing: Every valve undergoes comprehensive testing, including high-pressure hydrostatic body and seat tests, meeting the highest Product Specification Levels (PSL 1 to PSL 4) and Performance Requirements (PR1 & PR2).
- Global Quality Assurance: Fully backed by API 6A, API Q1, and ISO 9001 certifications, ensuring our wellhead equipment meets the most stringent international safety and reliability standards for the oil and gas extraction industry.
