Key Parts of Ball Valves
Body: The body of the valve, made from stainless steel, is the outer casing and provides the main structure. It contains the internal parts and has connections (ports) for the pipeline.
Ball: The ball is the central component that controls the flow of fluid. It's a sphere with a hole through the middle, which aligns with the pipeline when the valve is open and is perpendicular to it when the valve is closed.
Stem: The stem is the part that connects the handle to the ball. When the handle is turned, the stem rotates the ball.
Seat: The seats are rings of softer material (often PTFE or another plastic) that form a seal between the ball and the body when the valve is closed. There are typically two seats, one on either side of the ball.
Seals: Seals or packing material are used to prevent leakage along the stem. They ensure that when the valve is closed, no fluid can escape.
Bonnet: The bonnet is a part of the valve body that holds the stem. It's often bolted onto the body and provides a seal to prevent leaks.
