A ball valve is a type of shut-off valve that controls the flow of a liquid or gas using a rotating ball with a bore (hole) through it. When the ballβs hole is aligned with the flow, the valve is open. When itβs perpendicular, the valve is closed.
π§ Key Features of a Ball Valve:
Quick shut-off: Just a 90-degree turn to fully open or close.
Tight seal: Excellent for creating a leak-proof seal.
Durable: Suitable for high-pressure and high-temperature applications.
Low maintenance: Less wear and tear compared to gate or globe valves.
π§± Common Components:
Handle/lever β for manual operation.
Body β housing of the valve (metal, plastic, etc.).
Ball β with a hole in the center.
Seats β seals that the ball presses against.
Stem β connects the ball to the handle.
π οΈ Common Uses:
Residential plumbing (e.g., water shutoff)
Oil and gas industry
Chemical and petrochemical plants
HVAC systems
π Types of Ball Valves:
Full port (full bore) β No restriction in flow.
Standard port β Slightly reduced flow path.
Reduced port β Even more restricted flow.
V-port β Precise flow control.
Trunnion-mounted β For high-pressure system
