Shanghai Zhibang Valve Manufacture Co., Ltd. has been a trusted manufacturer of high-pressure fluid control solutions since 2016. Our CBT3191-92 High Pressure Ball Valve is specifically engineered for the demanding conditions of offshore oil and gas applications, where reliability and safety are paramount. With a robust design and rigorous quality control, this ball valve delivers superior sealing performance and long service life even in extreme environments. Backed by our ISO9001 certified production system, each valve undergoes thorough testing to ensure it meets the highest industry standards.
The CBT3191-92 series is built to withstand high pressures and corrosive media, making it an ideal choice for subsea pipelines, platform manifolds, and wellhead control systems. Its compact structure and low torque operation reduce installation and maintenance costs, while the fire-safe design and anti-static devices provide additional layers of safety. Whether you need a valve for critical isolation or throttling applications, the CBT3191-92 offers consistent performance under the most challenging offshore conditions.
Key Features & Technical Specifications
- High Pressure Rating: Designed for Class 1500 to 2500, suitable for extreme pressure environments.
- Full Bore or Reduced Bore: Available in both configurations to optimize flow efficiency.
- Fire-Safe Design: Meets API 607 / ISO 10497 standards for fire safety (optional certification available upon request).
- Anti-Static Device: Prevents static charge buildup, ensuring safe operation in explosive atmospheres.
- Blowout-Proof Stem: Enhances safety by preventing accidental stem ejection.
- Seat Material Options: PTFE, PEEK, or Nylon – customizable based on media and temperature requirements.

Advantages & Customer Benefits
The CBT3191-92 ball valve is designed to minimize downtime and maintenance costs in offshore installations. Its corrosion-resistant coating and advanced sealing technology ensure reliable operation in saltwater and sour gas environments. The valve’s quarter-turn operation allows rapid opening and closing, which is critical for emergency shutdown systems. Additionally, the modular design enables easy replacement of seats and seals without removing the valve from the pipeline, reducing maintenance time by up to 50%.
For our clients in the oil and gas industry, this means increased operational safety, lower total cost of ownership, and compliance with international standards such as API 6D, ASME B16.34, and NACE MR0175 (where applicable). The valve also features a locking device and position indicator for clear visual status.
