Specialist selection guide
What should be reviewed before selecting this valve?
A ball valve is a quarter-turn valve used for rapid isolation. Its straight flow path and 90-degree ball movement support low pressure loss and fast operation. Correct selection depends on body construction, ball design, seat arrangement, trapped-cavity pressure relief, fire-safe requirements and material compatibility with the process fluid.
Technical selection path
- 1
Choose full or reduced bore based on pressure drop and pigging requirements
- 2
Evaluate floating or trunnion-mounted construction against size, pressure and operating torque
- 3
Select soft or metal seats for the temperature, solids content and leakage class
- 4
Confirm antistatic, fire-safe and sealant-injection requirements
- 5
Match body, ball, stem and seal materials to corrosion and service temperature
Key strengths
- Fast isolation with quarter-turn operation
- Low pressure drop in full-bore designs
- Tight shutoff capability for many gas and liquid duties
Selection limitations
- Not the first choice for continuous throttling without suitable trim
- Trapped body-cavity fluid can thermally expand
- Soft seats are limited by high temperature and abrasive service
Typical applications
Where can this option be considered?
- Gas transmission and process liquid lines
- Emergency isolation and actuated systems
- Low pressure-drop duties

Common technical questions
Concise answers before enquiry
What is the difference between full-bore and reduced-bore ball valves?
A full-bore valve has a flow passage close to the pipe bore, reducing pressure loss and pigging obstruction. A reduced-bore valve can be smaller and more economical but introduces greater restriction.
When is a trunnion-mounted ball valve preferred?
At larger sizes or higher pressures, where fluid force and operating torque increase, trunnion support controls the load. Final selection must follow the manufacturer design and service conditions.
