Product Description
KOSO 501G 550G Cage Guided Globe Control Valves
Product Overview

The KOSO 501G and 550G are high-performance cage guided globe control valves, engineered to deliver precise fluid regulation for industrial applications. Built on KOSO’s decades of automation expertise, these valves feature a pressure-balanced trim design, ensuring stable operation even under harsh conditions like high pressure, temperature fluctuations, and cavitation risks. Ideal for critical process control, they combine durability, efficiency, and adaptability to meet the rigorous demands of modern industrial systems.

Features
  • Cage guided structure enhances dynamic stability and reduces wear for long-term reliability.
  • Pressure-balanced trim minimizes operating force, enabling smooth and precise flow control.
  • 550G’s multi-hole cage design achieves low noise and anti-cavitation performance.
  • Interchangeable parts between 501G and 550G simplify maintenance and inventory management.
  • Wide range of body and trim materials resists corrosion and harsh media.
  • Broad size and pressure rating options fit diverse pipeline and process requirements.
  • Compatible with various actuators (pneumatic, electronic, electro-hydraulic) for flexible automation integration.
