Detailed explanation of main features

Valve body and Material

Forging structure: The main pressure-bearing components of the valve body are manufactured by forging process. Compared with cast valves, forged steel valves have higher mechanical strength, better crystal phase structure and stronger impact and fatigue resistance, and are especially suitable for high-pressure and hazardous media.

Material A105: This is a carbon steel forging material grade under the ASTM standard and is one of the most commonly used and standard materials for manufacturing high-temperature and high-pressure valves. It features excellent mechanical properties and high-temperature resistance, and is typically used in a temperature range of -29°C to 425°C.

Sphere support method

Fixed ball core: This is the core design of this valve. The sphere is rigidly supported by two fixed shafts at the top and bottom, and will not shift during operation. This structure enables:

High-pressure application: It can withstand extremely high pipeline pressure, and the valve seat will not undergo excessive deformation due to medium pressure.

Low-torque operation: Even under high pressure, the opening and closing torque is much lower than that of floating ball valves, facilitating the configuration of large actuators.

Long service life: The opening and closing process causes little wear on the valve seat, significantly extending the service life of the valve.

Flow channel design

Full bore: The diameter of the channel inside the valve is basically the same as the nominal bore of the connected pipeline. This design enables:

Zero pressure loss: There is almost no pressure drop when the medium flows through the valve.

Ball passing capacity: Allowing pipe cleaners or pigging balls to pass through is crucial for pipelines that require regular cleaning.

Pressure rating

High pressure: This design usually complies with the standards of ANSI Class 600, 900, 1500 or higher pressure grades and can be applied to high-pressure working conditions in industries such as petroleum, natural gas, and chemical engineering.

Connection method

Flange connection: It is connected to the pipeline system through a flange plate and fastened with bolts. This is the most commonly used and reliable connection method in high-pressure large-diameter pipelines, which is convenient for installation, disassembly and maintenance, and has reliable sealing performance.

Summary of Advantages

High strength and safety: The forged steel A105 valve body and fixed structure ensure the integrity and safety of the valve under high pressure, high temperature and impact load.

Excellent sealing performance: The fixed design ensures that the valve seat is evenly stressed under high pressure, providing reliable sealing performance and a low risk of internal leakage.

Low flow resistance and high flow capacity: The full bore design minimizes energy loss during medium flow to the greatest extent.

Easy to operate and durable: Suitable for frequent operation, with low maintenance costs and high cost-effectiveness throughout its life cycle.

Versatility: It can be easily configured with gearboxes, pneumatic, hydraulic or electric actuators to achieve remote automatic control.

Typical application scenarios

This valve is an ideal choice for the following demanding industrial fields:

Oil and gas: long-distance pipelines, wellhead installations, and high-pressure process pipelines in oil refineries.

Chemical engineering and petrochemicals: High-pressure reaction equipment, cutting off corrosive or toxic media.

Energy and power: High-pressure steam and water supply systems of power stations.

Marine Engineering: Submarine Pipeline systems.

Any operating conditions that require zero pressure loss, high-pressure cut-off and high reliability.

Conclusion

This flange-connected full-bore high-pressure A105 forged steel fixed ball valve represents a heavy-duty industrial valve solution for critical operating conditions. By combining the superiority of forged materials, the stability of fixed spheres and the smoothness of full-bore design, it provides safe, efficient and long-life fluid control guarantees for modern industrial pipelines.
