Stainless Steel DBB Floating Ball Valve
Main Features
Double Block and Bleed Function: There are two independent sealing surfaces inside the valve, which can block the flow of the medium from both sides simultaneously and release the pressure through the intermediate bleed port, ensuring safety during pipeline maintenance and inspection.
Compact Design: Despite integrating multiple functions, the valve has a compact structure and is convenient to install, especially suitable for occasions with limited space.
Low Torque Operation: The floating ball valve design results in a relatively low operating torque, facilitating manual or automated operation.
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 threaded connection to meet different installation requirements.
Full Bore and Reduced Bore Design: It offers both full bore and reduced bore designs, which can be selected according to the flow requirements.
