Products Description
DBB 3 Pieces trunnion ball valve is a high-performance ball valve whose key feature lies in its trunnion-mounted ball design. This structure ensures the ball remains centered within the valve body during operation, eliminating sliding friction between the ball and seats. This significantly reduces torque requirements while enhancing sealing performance and service life.
The main functions of a DBB 3 Pieces trunnion-mounted ball valve include the following aspects:
Flow Control: By opening or closing the ball valve, the flow rate of fluid in the pipeline can be controlled, thereby regulating the pipeline's flow velocity and pressure.
Preventing Backflow: The ball valve can prevent fluid from flowing backward in the pipeline through its structural design, ensuring the safe operation of the pipeline system.
Reducing Pipeline Resistance: The ball valve has a simple structure and low flow resistance, which helps reduce resistance in the pipeline system, decrease energy consumption, and improve the efficiency of the pipeline system.
Key Features
Low-Torque Operation: The fixed ball design minimizes friction, reducing operating torque and enabling easier automation.
Reliable Sealing: Tight ball-to-seat contact, combined with bearing support, ensures leak-proof performance under high pressure.
Extended Lifespan: Reduced wear between the ball and seats lowers maintenance costs and prolongs service life.
Bidirectional Sealing: Most trunnion ball valves are designed for bidirectional sealing, accommodating flow in either direction.
Wide Pressure Range: Suitable for various pressure ratings, from low to high-pressure applications.
Applications
Trunnion ball valves are widely used in:
Oil & Gas Industry: Controlling crude oil, natural gas, and other media to ensure pipeline safety.
Chemical Industry: Handling corrosive, flammable, or explosive fluids safely.
Power Generation: Regulating media in boilers, turbines, and other critical systems.
Water Treatment: Managing water flow in supply and drainage systems.
Other Industries: Metallurgy, pharmaceuticals, food processing, and more.
This versatile valve is ideal for demanding industrial environments where reliability, durability, and precision are paramount.
