Technical Data Sheet
Product: 2‑Piece Floating Ball Valve
Size / Rating: 6″ – Class 150 – RF (Raised Face)
Construction: 2‑Piece
Matériau du corps : A105 (Carbon Steel)
- General Description
This 2‑piece floating ball valve features an A105 carbon steel body constructed from a main body and an end piece joined by bolts. The 2‑piece design offers compact dimensions, reliable sealing, and easy maintenance. It is suitable for water, oil, gas, steam, and mild corrosive media in industrial piping systems. With its 6‑inch size, it handles high‑flow applications and can be equipped with a gearbox or actuator for automated control.

- Caractéristiques principales
4.1 2‑Piece Construction Advantages
- Compact design – Fewer flange connections result in shorter overall length and lighter weight, requiring less installation space.
- Easy maintenance – Remove the end piece bolts to access the ball, seats, and stem for inspection or replacement without removing the valve from the pipeline.
- Reliable sealing – Precision‑machined body joint with a gasket ensures leak‑tight sealing.
4.2 Floating Ball Sealing Performance
- Low flow resistance – Full‑port design offers minimal pressure drop.
- Quarter‑turn operation – Fast 90‑degree operation suitable for frequent cycling.
- Bidirectional sealing – Upstream pressure forces the ball against the downstream seat for reliable zero‑leakage shut‑off.
4.3 Safety & Operation
- Anti‑static design – A grounding spring ensures electrical continuity between stem, ball, and body to prevent static buildup.
- Blowout‑proof stem – Stem is designed to prevent ejection under pressure.
- Operation options:
- 6″: Lever with lock (standard)
- Worm gearbox optional – Reduces operating torque for easier manual operation
- ISO 5211 actuator mounting pad available for pneumatic/electric actuators

- Installation & Maintenance Notes
6.1 Installation Precautions
- Flow direction – Bidirectional; installing according to the body arrow is recommended to maximize seat life.
- Flange installation – Use appropriate gaskets (spiral wound recommended). Tighten bolts evenly in a cross pattern.
6.2 Maintenance & Repair
- Packing adjustment – If slight leakage occurs at the packing, carefully tighten the packing gland. If leakage persists, replace the packing.
- Seat / ball replacement:
- Close the valve and depressurize the line
- Remove end piece bolts and separate the end piece
- Extract ball, seats, and stem assembly
- Replace worn components and reassemble in reverse order
Bolt torque – When assembling the body joint, tighten bolts in a cross pattern in multiple stages to ensure even gasket compression.- Approximate Dimensions (for reference)
