A ball valve is a quarter-turn valve in which a drilled ball rotates between seats, allowing straight-through flow in the open position and shutting off flow when the ball is rotated 90° and blocks the flow passage.
Recommended
● For on-off, nonthrottling service
● Throttling service with special trim
● Where quick opening is required
● Where minimum resistance to flow is needed
Applications
● General service, high temperatures, cryogenic service, slurries
Advantages
● Low cost
● High capacity
● Bidirectional shutoff
● Straight-through pattern
● Low leakage
● Self-cleaning
● Low maintenance
● No lubrication requirement
● Compact
● Tight sealing with low torque
● Good throttling characteristics with special trim
Disadvantages
● Poor throttling characteristics with standard ball designs
● Susceptible to seal wear with soft seats
● Prone to cavitation with standard ball designs
Variations
● Construction: top entry, split body, end entry, or welded
● Style: floating ball, trunnion mounted, rising stem, or throttling
