3-Piece Threaded Stainless Steel Ball Valve

⚙️ Design and Features

1. 3-Piece Body Construction: The valve body is constructed from three separate pieces: a main body section and two end caps.

   • Advantage: This design allows the central body (containing the ball and seats) to be completely removed from the pipeline by simply loosening the body bolts, without having to disconnect the end caps from the piping. This is a major benefit for in-line maintenance and seat/seal replacement.

2. Connection Type: Threaded:

   • The end caps feature internal threads (typically NPT or BSP) for quick and easy screw-in connection to the pipeline.

   • Advantage: Simple installation without welding or flanges, suitable for small to medium pipe sizes.

3. Material: Stainless Steel (SS):

   • The valve is cast from Stainless Steel (commonly SS304 or SS316), providing excellent corrosion resistance against water, oil, gas, steam, and many chemicals.

4. Ball & Seating:

   • Uses a spherical ball with a bore through the center to control flow.

   • PTFE (Polytetrafluoroethylene) seats are standard, offering tight sealing, low operating torque, and good temperature and chemical resistance.

⭐ Key Advantages

• Serviceability: Superior to 1-piece or 2-piece designs, as it drastically reduces downtime and labor costs for maintenance.

• Full Flow: Available in both Reduced Bore and Full Port designs, with the latter offering minimal pressure drop and full pipeline flow when open.

• High Pressure/Temperature: Built to handle moderate to high pressures and temperatures, depending on the specific PTFE seat material used.

🏭 Typical Applications

• Chemical Processing
