Flanged Floating Ball Valve
Flanged Floating Ball Valve is selected for asme flanged process piping where bolted removal and standard flange connections are required. A flanged floating ball valve combines a floating ball-and-seat arrangement with RF or other specified flange ends. It is widely used in process and utility piping because it can be removed from the line without cutting the pipe and can be matched to the project flange standard and pressure class.

When to select this design
ASME flanged process piping where bolted removal and standard flange connections are required.
Choose this design when standard flanged installation and easy line removal are more important than welded-end integrity.
Typical applications
- Refining utilities
- Process plants
- Terminal piping
- Water and industrial service

Flanged Floating Ball Valve: design points to confirm.
This is a specific valve construction. Final size, class, material and seat combinations depend on the approved datasheet and design calculation.
| Body construction | Floating ball construction with flanged end connections provides a removable line valve for many process systems. Body style can vary by size and pressure class, but flange compatibility is a primary selection input. |
|---|---|
| Seat & sealing | Seat selection controls pressure-temperature capability and operating torque. PTFE, reinforced PTFE, nylon, PEEK or other materials may be considered according to the actual design and service. |
| End connection | Confirm RF or other flange facing, ASME flange standard, pressure class, drilling and face-to-face dimensions. Mating flange compatibility should be checked before final approval. |
| Engineering focus | The floating ball creates seat loading from line pressure, so practical size/pressure range and torque must be checked rather than assuming one design covers all classes. |
| Material selection | WCB, low-temperature carbon steel or stainless steel body materials may be considered depending on piping class. Trim and soft parts should be specified separately. |
| Testing & inspection | Include shell/seat test standard, fire-safe and emission requirements where applicable, plus dimensional checks for flange and face-to-face compliance. |

Construction and maintenance
Floating ball construction with flanged end connections provides a removable line valve for many process systems. Body style can vary by size and pressure class, but flange compatibility is a primary selection input.
Seat, sealing and torque
Seat selection controls pressure-temperature capability and operating torque. PTFE, reinforced PTFE, nylon, PEEK or other materials may be considered according to the actual design and service.
Piping and installation
Confirm RF or other flange facing, ASME flange standard, pressure class, drilling and face-to-face dimensions. Mating flange compatibility should be checked before final approval.
What to verify before approving the technical offer.
Engineering risk
The floating ball creates seat loading from line pressure, so practical size/pressure range and torque must be checked rather than assuming one design covers all classes.
Materials and traceability
WCB, low-temperature carbon steel or stainless steel body materials may be considered depending on piping class. Trim and soft parts should be specified separately.
Inspection and testing
Include shell/seat test standard, fire-safe and emission requirements where applicable, plus dimensional checks for flange and face-to-face compliance.
Send the valve datasheet together with the piping class and project valve, material, testing and coating specifications. Missing design inputs should be clarified rather than assumed.
