Versatile and Reliable Construction

Cast from premium materials like WCB, LCB, CF8, CF8M, A105, F304, and F316, the trunnion mounted ball valve is built for reliability in harsh environments. Its construction supports both soft and metal seated designs, with optional PTFE or epoxy coatings for enhanced corrosion resistance. The anti-blow-out stem and anti-static device improve safety during operation.

Certified for Safety and Performance

Designed under globally recognized standards including API 6D, ASME B16.34, and equipped with API 607 Fire Safe certification, these ball valves ensure exceptional performance and dependable fire-safe operation. Testing in accordance with API 598 further confirms their leak-tight and robust sealing abilities under various pressures.

Flexible Operation and Automation

Choose from manual levers, gear mechanisms, or electric, pneumatic, and hydraulic actuators. Each valve includes an ISO 5211 mounting pad for easy integration with automated control systems, allowing for remote, automatic, or manual operation, tailored to varied industrial processes.

FAQ's of Cast Trunnion Mounted Ball Valve:

Q: How does a cast trunnion mounted ball valve enhance operational safety and reliability?

A: These valves include features such as a blowout-proof stem, anti-static device, API 607 fire-safe certification, and a locking device for safety. Their trunnion-mounted design supports the ball under high pressure, preventing excessive seat wear and potential leakage, making them highly reliable in critical applications.

Q: What process standards govern the manufacturing and testing of these ball valves?

A: Design, manufacturing, and testing conform to international standards including API 6D, ASME B16.34 for construction, ASME B16.10 for face-to-face dimensions, and ASME B16.5/B16.25 for end connections. Performance and sealing are validated through rigorous testing by API 598 and API 6D protocols.

Q: When should a trunnion mounted ball valve be selected over a floating ball valve?

A: Trunnion mounted ball valves are ideal for high-pressure or large diameter pipelines, commonly found in oil & gas, petrochemical, power plants, and water treatment applications. Their design minimizes seat wear, enhances sealing under fluctuating pressures, and ensures stable operation over long cycles.

Q: Where are these cast trunnion mounted ball valves typically installed?

A: These valves are widely installed in pipelines and critical systems within oil refineries, petrochemical plants, water treatment facilities, power generation stations, and other industrial operations requiring tight shutoff and reliable flow control in high-pressure and high-temperature conditions.

Q: What types of end connections and port sizes are available?

A: Available end connections include flanged (RF/RTJ), butt weld, and socket weld as per ASME standards. Port options include full bore and reduced bore designs, with valve sizes ranging from 2 to 48 inches (DN50 to DN1200) for compatibility with various pipeline requirements.

Q: How can automation and remote operation be implemented with these ball valves?

A: Every valve is equipped with an ISO 5211 mounting pad for seamless integration of electric, pneumatic, or hydraulic actuators, enabling automated or remote control. This allows adaptation to modern process control systems for enhanced efficiency and safety in plant operations.
