Floating Ball Valves: The Pinnacle of Industrial Flow Control and Safety
The floating ball valve is a high-quality valve designed for maximum service life and reliability in various industrial applications. The design and manufacturing process of these valves adhere to a range of international standards, ensuring their performance and safety.
Floating Ball Valves Dimensions:
Applicable Standards:
The floating ball valves meet the API 6D, BS 5351, and ASME B16.34 standards, which are recognized globally for their rigorous requirements in terms of design, materials, and testing.
The API 608 and API 6D standards specifically pertain to steel ball valves, ensuring quality and consistency.
The ISO 10434 and ISO 14313 standards relate to fire durability, which is critical for safety in potentially explosive environments.
The ASME B16.34 standard covers the design of steel valves, including anti-static features and face-to-face dimensions.
The ASME B16.5 and ASME B16.25 standards address end flanges and buttwelding ends, respectively, ensuring compatibility with various piping systems.
API 598 and API 6D cover inspection and testing procedures to ensure the valves meet the required standards.
Range of Materials:
The standard materials for the body and cap of floating ball valves include carbon steel, low alloy steel, and various grades of stainless steel.
For specialized applications, other materials such as higher grades of alloy steel and stainless steel can be supplied.
A comprehensive range of trim materials is available to suit any service condition, ensuring the valve's longevity and performance.
Design Description:
The full port design of the floating ball valve allows for exceptional flow control without restrictions.
The valve features a bolted cap and a split body for easy disassembly and maintenance.
The floating ball type with a blow-out proof stem ensures safety against excess pressure.
Fire durable construction and anti-static devices are included to meet the highest safety standards.
The ISO 5211 mounting pad ensures compatibility with a range of actuator types.
Flanged or buttwelding ends provide flexibility in piping systems.
Operating:
The valve can be operated with an extended lever for manual control or with gearing, motor actuators, pneumatic, or hydraulic actuators for more challenging services.
Bore:
The valve is available in full bore or reduced bore designs. The full bore design provides unrestricted flow, which is particularly beneficial for applications requiring high flow rates.
End Connections:
The choice of flanged, RTJ flange, or butt-welding ends allows for versatile piping connections.
Body & Cap:
The split or 2-piece design allows for easy disassembly and maintenance of the internal components.
Packing:
Standard packing includes multiple VPTFE packing, which maintains compression even under high-cycle and severe service conditions.
Graphite packing is suitable for high-temperature applications.
Blow-Out Proof Stem (BPS):
The blow-out proof stem design protects against failure under excess pressure, ensuring the valve's integrity.
Anti-Static (AS):
The valve is designed with a metallic contact between the ball, stem, and body to prevent static build-up and ensure safety.
Fire Durability (FD):
The fire durable design meets API 607 or BS 6755 standards, ensuring the valve's operability in the event of a fire. The secondary metal-to-metal seal acts as a backup in case the primary seal is compromised.
Overall, the floating ball valve is a robust and reliable solution for industrial flow control applications, offering a range of features and materials to meet the diverse needs of the industry.
