The Gear Operated DBB Ball Valve is designed for chemical injection systems, providing reliable isolation and leak prevention. It combines double block and bleed (DBB) functionality with gear operation, ensuring smooth control even in high-torque applications. The valve offers flexible installation with both Buttweld (BW) and Socket Weld (SW) connections.
With an anti-static design, it reduces the risk of static buildup when handling flammable chemicals, enhancing safety. Made from high-quality materials, the valve is built to withstand harsh industrial environments, making it a reliable choice for chemical injection in sectors like oil and gas, petrochemicals, and chemical processing.
● Anti-Static Design: Prevents static buildup, ensuring safe operation when handling flammable or volatile chemicals.
● Double Block and Bleed (DBB) Functionality: Provides two layers of isolation, enhancing leak prevention and safety during maintenance.
● Flexible Connection Options: Available with both Buttweld (BW) and Socket Weld (SW) connections for easy integration into various systems.
● Gear Operated Mechanism: Ensures smooth operation, especially in larger valve sizes or applications requiring higher torque.
