2-Piece Floating Ball Valve
2-Piece Floating Ball Valve is selected for general process isolation where a compact body and straightforward flanged or threaded installation are preferred. A 2-piece floating ball valve uses a body-and-end-piece construction that keeps the valve compact while allowing a wide range of end connections and materials. It is commonly considered for process, utility and terminal service when line size and pressure remain within the practical range of a floating-seat design.

2-Piece 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 | Two-piece body-and-end-piece construction. The compact layout is commonly used for flanged or threaded process valves where full center-body removal is not the main maintenance requirement. |
|---|---|
| Seat & sealing | Soft seats such as PTFE or reinforced PTFE are common for suitable pressure-temperature duties. Seat material must be checked against media, temperature, fire-safe construction and operating torque. |
| End connection | RF flanged or threaded ends are common depending on size and piping class. Confirm flange standard, face-to-face requirement and whether lever or gear operation is required. |
| Engineering focus | Check body joint sealing, seat pressure-temperature capability and stem packing against the actual service. For automated valves, actuator sizing should include break torque and project safety margin. |
| Material selection | Common project materials may include carbon steel or stainless steel bodies with stainless trim. The exact body, ball, stem, seat and seal combination should follow the piping class and corrosion requirements. |
| Testing & inspection | Specify shell and seat testing, fire-safe qualification where required, fugitive-emission requirements and any PMI or NDE required by the project. |
Engineering considerations for 2-Piece Floating Ball Valve.
Construction and maintenance
Two-piece body-and-end-piece construction. The compact layout is commonly used for flanged or threaded process valves where full center-body removal is not the main maintenance requirement.
Seat, sealing and torque
Soft seats such as PTFE or reinforced PTFE are common for suitable pressure-temperature duties. Seat material must be checked against media, temperature, fire-safe construction and operating torque.
Piping and installation
RF flanged or threaded ends are common depending on size and piping class. Confirm flange standard, face-to-face requirement and whether lever or gear operation is required.
What to verify before approving the technical offer.
Engineering risk
Check body joint sealing, seat pressure-temperature capability and stem packing against the actual service. For automated valves, actuator sizing should include break torque and project safety margin.
Materials and traceability
Common project materials may include carbon steel or stainless steel bodies with stainless trim. The exact body, ball, stem, seat and seal combination should follow the piping class and corrosion requirements.
Inspection and testing
Specify shell and seat testing, fire-safe qualification where required, fugitive-emission requirements and any PMI or NDE required by the project.
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.
