Flanged Angle Globe Valve

Overview:

The Flanged Angle Globe Valve is designed for applications where the pipeline changes direction, providing flow regulation and shut-off functionality in a compact design. By incorporating a 90-degree angle in its construction, this valve reduces the need for additional pipe fittings, simplifying system layout and minimizing space requirements. It is widely used in industries like oil and gas, chemical processing, power generation, and water treatment.

Product Features:

1. Design and Construction:
   • 90-Degree Angle Body: The unique right-angle design eliminates the need for elbows or additional fittings, simplifying the pipeline layout and reducing pressure loss.
   • Flanged Connection: Features flanged ends for easy installation and secure, leak-proof connections with the piping system, complying with standard flange specifications like ANSI, DIN, or JIS.
   • Globe Valve Disk: The disk moves perpendicular to the flow, providing accurate flow regulation and effective shut-off, making the valve suitable for throttling as well as on/off control.
2. Material:
   • Valve Body: Typically made from carbon steel, stainless steel, or cast iron, depending on the application’s requirements, offering corrosion resistance and durability in a wide range of environments.
   • Sealing Materials: Available with various sealing options, including PTFE, graphite, or metal-to-metal sealing, to accommodate different media and temperature ranges.
3. Flow Control:
   • Efficient Flow Regulation: The valve’s design allows for precise control of flow, making it suitable for throttling operations in pipelines where flow control is critical.
   • Low-Pressure Drop: The angled design reduces turbulence and pressure drop compared to standard globe valves, making it more efficient in applications with directional flow change.
4. Pressure and Temperature Ratings:
   • Pressure Range: Typically available in pressure classes from PN16 to PN100 or ANSI Class 150 to 600, making it suitable for both low and high-pressure systems.
   • Temperature Range: The valve can handle a wide range of temperatures, from -29°C to 425°C, depending on the materials used for the valve body and seals.
5. Stem Design:
   • Rising or Non-Rising Stem: Available with either a rising stem, which provides a clear visual indication of the valve’s position, or a non-rising stem to save space in applications where vertical clearance is limited.
   • Stem Sealing: The valve features reliable stem sealing with packing options like PTFE or graphite, ensuring a tight seal and preventing stem leakage.
6. Operation:
   • Manual or Automated: The valve can be operated manually with a handwheel or equipped with electric, pneumatic, or hydraulic actuators for remote or automated control.
   • Easy Operation: The angle design and flow path minimize the effort required to operate the valve, reducing wear and tear on components.
7. Compact Design:
   • The flanged angle globe valve is compact, with fewer installation points than traditional valves with separate elbow fittings, making it ideal for applications with space constraints.

Applications:

1. Oil and Gas:
   • Used in refineries and pipelines where space optimization and reliable flow control are essential, especially in directional flow changes.
2. Chemical Processing:
   • Effective in corrosive or aggressive media, where the valve’s material and sealing options offer durability and leak-tight performance.
3. Power Generation:
   • Installed in steam and condensate systems, where accurate flow control is required under high temperatures and pressures.
4. Water Treatment:
   • Common in water and wastewater treatment plants for controlling the flow of liquids in systems that require 90-degree directional flow changes.
5. Pharmaceuticals:
   • Used in processes requiring high purity standards and precise flow control for liquids and gases.

Advantages:

• Space-Saving Design: The right-angle body design allows for a more compact installation, reducing the need for additional fittings and saving space in complex piping systems.
• Precise Flow Control: Offers better throttling performance compared to many other valve types, making it ideal for applications that require fine control of flow rates.
• Reduced Pressure Loss: The angle design minimizes pressure drop and turbulence, leading to a more efficient flow with lower energy consumption.
• Versatile Installation: The flanged connection simplifies installation and maintenance, allowing for easy integration into existing systems.

Conclusion:

The Flanged Angle Globe Valve is a versatile and efficient solution for controlling flow in pipelines with directional changes. Its compact design, precise flow control, and wide range of materials and pressure ratings make it suitable for a variety of industrial applications. Whether used in high-pressure steam systems or in corrosive chemical environments, this valve provides reliable performance and durability.
