Forged Steel Full Bore Fully Welded Trunnion Ball Valve with Gear Box
Main Features
Fully Welded Structure: The valve body adopts a fully welded process without bolt connections, enhancing the overall strength and sealing performance of the valve, and it is especially suitable for high-pressure and high-temperature working conditions.
Stem Design: The valve stem is supported by bearings, which reduces the operating torque and improves the stability and reliability of the valve.
Full-bore Design: The internal flow passage is unobstructed, allowing the medium to flow smoothly with low pressure loss, and it is suitable for pigging operations.
Gearbox Operation: Equipped with a gearbox, it has a small operating torque, operates smoothly and reliably, and is suitable for the operation of large-diameter valves.
Fire Safety Design: It complies with the API 607 fire safety standard and can maintain its sealing performance in extreme situations such as fires.
Anti-static Device: It has a built-in anti-static device to ensure electrical continuity among the valve stem, ball, and valve body, reducing the safety risks caused by static electricity.
Anti-blowout Valve Stem Design: The valve stem design includes a protective sleeve to prevent the valve stem from being blown out under high pressure.
Low Emission Design: It adopts low-emission packing, meeting environmental protection requirements.
Multiple Connection Methods: It provides various end connection methods such as flange connection and butt welding connection to meet different installation requirements.
