Overview
A 3-piece flanged ball valve is a quarter-turn shut-off device designed for high-pressure systems. It features a stainless steel or carbon steel body constructed from three distinct sections bolted together. This design adheres to ANSI/ASME standards, ensuring robust sealing and easy maintenance without removing the valve from the pipeline.
Application
- Petrochemical processing plants requiring reliable isolation.
- Water treatment facilities managing corrosive fluids.
- Oil and gas transmission networks handling high flow rates.
- Power generation systems controlling steam and coolant cycles.
Precautions
- Ensure gaskets are replaced during every disassembly to prevent leaks.
- Regularly inspect stem seals for wear under high-temperature conditions.
- Verify torque specifications on flange bolts to maintain structural integrity.
- Schedule periodic lubrication of internal moving parts to ensure smooth operation.
