KOSO 521F 522F 3 Way Diverting Mixing Globe Valves 500A 520A Top Guided Single Seated Angle Vlaves

This product line includes two high-performance valve series from KOSO: the 521F/522F 3-way diverting/mixing globe valves and the 500A/520A top-guided single-seated angle valves. Designed for industrial process control, these valves combine precision, durability, and versatility to meet the diverse needs of fluid regulation. The 521F/522F series specializes in diverting or mixing fluid streams with reliable switching performance, while the 500A/520A series excels in high-precision flow control in space-constrained or high-pressure applications, featuring a compact angle design and stable top-guided structure.

• Dual-function design: Compatible with both diverting (splitting one fluid stream into two) and mixing (combining two streams into one) applications, reducing equipment costs.
• Precise flow distribution: Optimized valve core design ensures uniform fluid distribution, minimizing pressure loss and maintaining stable flow rates.
• Stable operation: Rigid valve stem and precision guiding structure prevent vibration and leakage, extending service life under continuous operation.
• Corrosion-resistant options: Multiple body and trim material selections to adapt to acidic, alkaline, and other corrosive media.
• Easy maintenance: Split-body design allows convenient disassembly and maintenance without removing the entire valve from the pipeline.

• Top-guided structure: Ensures accurate valve core positioning, low friction, and stable travel, improving control precision.
• Single-seated design: Provides excellent sealing performance, meeting strict leakage standards for critical process applications.
• Angle flow path: 90-degree angle design reduces flow resistance, prevents media accumulation, and is suitable for high-viscosity or solid-containing fluids.
• Compact size: Space-saving structure, easy to install in narrow pipelines or equipment compartments.
• High pressure adaptability: Reinforced body structure and pressure-resistant trim enable reliable operation under high differential pressure conditions.

Both valve series are widely used in various industrial fields requiring precise fluid control, with targeted applications for each series as follows:

• Petrochemical industry: Diverting/mixing of crude oil, refined oil, and chemical solvents.
• Thermal power plants: Mixing of cold and hot water, diverting of steam and condensate.
• Chemical industry: Mixing of reaction materials, diverting of waste liquid and clean water.
• Food and beverage industry: Mixing of raw materials, diverting of finished products and cleaning fluids (food-grade material optional).
• HVAC systems: Temperature regulation through mixing/diverting of hot and cold air or water.

• Oil and gas industry: Flow control of wellhead gas, crude oil gathering and transportation, and high-pressure pipelines.
• Metallurgy industry: Control of cooling water, steam, and molten metal auxiliary fluids.
• Chemical industry: Precision control of corrosive media, high-viscosity fluids, and toxic gases.
• Pharmaceutical industry: Sanitary-grade flow control (with special polishing and material selection).
• General industrial: Space-constrained pipelines, such as boiler systems, pump outlet control, and small-scale process equipment.

• Q: What is the main difference between the 521F and 522F valves? A: They share the same 3-way diverting/mixing core design. The key difference lies in nominal pressure range and body structure: 521F is suitable for medium-pressure applications, while 522F is designed for high-pressure working conditions with a reinforced body.
• Q: Can the 500A and 520A valves be used for high-temperature steam? A: Yes. With high-temperature resistant packing and trim materials (such as alloy steel and ceramic), they can reliably operate with steam up to 550°C.
• Q: Are the 3-way valves (521F/522F) compatible with both diverting and mixing modes? A: Yes. The valve core can be adjusted according to installation requirements, supporting both diverting (one inlet to two outlets) and mixing (two inlets to one outlet) functions without replacing the valve body.
• Q: Do you provide replacement parts and maintenance services for these valves? A: Yes. We supply original-equivalent trim, gaskets, packing, and actuators, as well as professional technical guidance for installation, disassembly, and maintenance.
• Q: Can these valves be matched with non-KOSO actuators or positioners? A: Yes. They are compatible with mainstream international brands of pneumatic and electric actuators, including Siemens, ABB, and Yamatake, as well as various types of valve positioners.
