Describe

DN600 Trunnion-Mounted Ball Valve

Product Type: Trunnion-Mounted Ball Valve (3-Piece Bolted Design)
Nominal Size: DN600 (24″)
Manufacturer: AOGONG VALVE
Connection Type: Flange End (ASME B16.5 standard configuration)
General Design: Full bore, metal-seated (configurable soft/metal combination seat), API 6D compliant

Trunnion-Supported Structure: The ball is supported by upper and lower trunnions, enabling the valve to withstand extremely high differential pressures without shifting, ensuring stable sealing and low leakage under severe service conditions.
Full Bore Design: The internal flow path matches the pipeline ID, minimizing flow resistance and pressure drop, making it ideal for high-flow media transmission.
Corrosion-Resistant Material: Stainless steel construction (e.g., ASTM A351 CF8) offers excellent resistance to corrosion, suitable for natural gas, petrochemical, and other corrosive or clean media applications.
High-Performance Sealing: Configurable metal-to-metal or soft/metal combination seats, capable of meeting ANSI/FCI 70-2 Class IV and higher leakage requirements for both gas and liquid services.
Modular Maintenance: The 3-piece bolted body design allows easy disassembly and replacement of internal components (ball, seats), reducing maintenance downtime and lifecycle costs.
Actuation Compatibility: The top flange interface is designed to accept pneumatic, electric, or hydraulic actuators, supporting both manual operation and automated remote control for industrial process systems.

This valve is widely used in critical industrial sectors:

Oil & gas long-distance transmission pipelines and city gas distribution networks
High-pressure petrochemical and refining process lines
Large-scale power plant and metallurgical media transmission systems
Water treatment and municipal large-diameter pipeline isolation services

Designed and manufactured in accordance with major international standards, including:
