KOSO 501T 551T 520T 511T Top Guided Single Seat Globe Valves for Oil Gas Fluid Regulation

KOSO 501T 551T 520T 511T Top Guided Single Seat Globe Valves

The KOSO 501T 551T 520T 511T Top Guided Single Seat Globe Valves are precision-engineered industrial control valves, optimized for accurate flow regulation in critical process systems. Featuring a robust top-guided single seat design, these valves deliver exceptional stability, low leakage, and reliable performance under high pressure, high temperature, and variable flow conditions. As a core offering in KOSO’s control valve portfolio, they are built to meet the stringent demands of industrial automation, with tailored configurations for diverse media and operating scenarios.

Features

• Top guided single seat structure ensures superior positional stability and precise flow control for small to medium flow rates.
• Multiple body designs (angle type for 501T, globe type for others) optimize flow path efficiency for different pipeline layouts.
• Ultra-low leakage performance (ANSI Class VI for soft seat) meets strict industrial sealing requirements.
• Wide range of trim materials (SUS316, Stellite) resist corrosion, wear and cavitation in harsh media environments.
• Customizable flow characteristics (linear, equal percentage, on-off, needle flow) for targeted process control needs.
• Broad pressure and temperature ratings adapt to extreme industrial operating conditions (-196~+538℃).
• Interchangeable spare parts simplify maintenance and reduce inventory costs for industrial users.
• Compatible with all standard KOSO pneumatic, electronic and electric actuators for flexible automation integration.
