Overview
A All welded fixed ball valve features a monolithic body constructed via full-penetration welding, eliminating external leakage paths. The fixed ball design utilizes upper and lower shafts to support the sphere, ensuring stable operation under high pressure.
Application
- Petrochemical: Main pipelines in refineries and gas transmission stations.
- Oil & Gas: Offshore platforms and subsea manifolds.
- Power Generation: Steam lines and feedwater systems in thermal plants.
- Chemical Processing: High-corrosive fluid transport in closed-loop reactors.
Precautions
- Temperature: Operate strictly within -46°C to +425°C range depending on material grade.
- Pressure: Adhere to ANSI Class 150-2500 ratings; avoid hydraulic shock.
- Maintenance: Perform annual seat integrity checks; replace seals only during shutdown cycles.
