The KOSO 400H Parallel Slide Valves are heavy-duty industrial valves engineered for precise flow control in high-pressure, high-temperature environments. Designed to meet stringent global standards, these valves deliver reliable performance and long service life in critical industrial processes.

• Wide pressure rating: ANSI Class 150/300, 600, 900/1500, 2500 and JIS 10K-30K, 40K, 63K
• Extreme temperature resistance: Operates from -196°C to +538°C for cryogenic and high-heat applications
• Multiple connection options: Flanged (RF, RTJ), butt weld, and socket weld for versatile installation
• Robust material construction: Body, disc, and seat materials include carbon steel, stainless steel, and alloy steel for durability
• High rangeability: Up to 30:1 for precise flow regulation across varying process demands
• ANSI Class V seat leakage: Ensures tight shut-off and minimizes fluid loss
• Actuator compatibility: Works with pneumatic diaphragm, pneumatic cylinder, and electric actuators for automated control

• Thermal power plants (boiler feedwater, steam, and condensate control)
• Oil and gas refineries (crude processing, distillation, and pipeline systems)
• Petrochemical industry (chemical processing, polymer production, and solvent handling)
• Industrial manufacturing (high-pressure fluid transfer and process regulation)
• Energy and utility sectors (power generation, district heating, and water treatment)
