Didtek Flange 6inch 2500LB Forged DBB Trunnion Ball Valves

Summary of Core Features

High pressure and large diameter

6 inches: Suitable for high-flow piping systems.

2500LB: High pressure rating, capable of withstanding harsh working conditions of approximately 42MPa.

High-strength structure

Forged valve body: Compared with casting, it has superior strength, toughness and impact resistance.

Ear shaft fixed type: The ball is fixed by the upper and lower shafts, with a small operating torque and smooth opening and closing. It is suitable for high-pressure and large-diameter applications, and there is no risk of the valve stem being blown out.

Key Safety Function - DBB:

Double blocking and discharge: When the valve is closed, the two valve seats upstream and downstream seal simultaneously, achieving double isolation. And the medium in the valve cavity can be drained through the relief valve, which is used for:

Safety isolation: Maintenance of equipment.

Online inspection: Verify the sealing performance.

Relieve pressure: Ensure operational safety.

Reliable connection and operation

Flange connection: Standard interface, firm installation, easy to disassemble.

Multiple drive modes: Supports manual (handle/worm gear), pneumatic, electric, etc., to meet different automation requirements.

Typical application scenarios

Due to its robust structure and high-pressure sealing performance, this valve is widely used in industrial fields with extremely high requirements for safety and reliability:

Petroleum and natural gas: Oil and gas pipelines, refining and chemical plants.

Electric power industry: High-temperature and high-pressure steam and water supply systems in thermal power stations.

Chemical Engineering and Metallurgy: Cutting off corrosive and high-risk media.

Other industries include papermaking, textile, water supply and drainage, energy, polysilicon, etc.

Summary and Application

This valve is the preferred isolation device in high-pressure, large-diameter pipeline systems with extremely high requirements for safety and reliability in industries such as oil and gas, chemical engineering, and power. Its forged ear shaft structure ensures the valve's robustness and durability, while the DBB function provides crucial operational safety and maintenance convenience. It is a truly high-end industrial valve designed for harsh environments.
