Q61F Forged Steel Three-Piece Ball Valve Overview
The Q61F Forged Steel Three-Piece Ball Valve is a high-performance compact ball valve featuring a forged steel body with internal thread or butt weld connections. Its body consists of three segments connected by high-strength bolts. The valve is precision-machined from forged steel materials (e.g., A105), and the ball is rotated 90 degrees via the stem for quick opening and closing. The sealing pair utilizes soft materials such as PTFE or a metal hard-seal configuration. This design combines high-pressure capability with a compact installation footprint, making it specifically suitable for applications in petrochemicals, power plants, high-pressure instrumentation, and piping systems with limited space. It is an ideal choice for reliable shut-off in small-bore, high-pressure operating conditions.

Q61F Forged Steel Three-Piece Ball Valve Features
1. Compact Forged Steel Body for High-Pressure Applications:
Utilizes a forging process to achieve dense material and high strength. Its compact design is suitable for small-bore, high-pressure pipelines, offering excellent pressure-bearing performance.
2. Convenient Maintenance with Three-Piece Structure:
The valve body consists of three bolted sections, enabling internal inspection and seal replacement of the middle body segment without completely removing the valve from the pipeline, thereby reducing maintenance costs.
3. Flexible and Reliable Connection Options:
Provides internal thread (NPT/G) or butt weld connections, meeting various high-pressure pipeline connection requirements with reliable sealing and stable installation.
4. Versatile and Superior Sealing Performance:
Standard soft sealing ensures zero leakage, while optional metal hard sealing is available for high-temperature or media containing particles, offering broad applicability.
5. Cost-Effective and Durable for Wide Applications:
Forged steel material provides corrosion resistance and long service life. The three-piece design reduces the total lifecycle maintenance cost, making it an optimal valve choice for small-bore, high-pressure pipelines.
