Ball Valves
Introduction
A ball valve is a type of quarter-turn valve that uses a hollow, perforated, and pivoting ball to control flow through it. Here’s a detailed overview of ball valves, including their construction, working principle, types, applications, and considerations:
Key Features:
Ball Structure:
The ball valve has a spherical closure element (the ball) with a hole in the middle, often
referred to as a bore.
When the bore is aligned with the valve body inlet and outlet ports, flow occurs. Rotating
the ball 90 degrees by the valve handle perpendicular to the flow direction blocks flow by
aligning the bore with the valve body's fluid passage and redirecting flow.
Actuation:
Ball valves are typically operated manually with a lever handle. When the handle is parallel
to the valve body, the valve is open, allowing fluid to flow through. When perpendicular,
the valve is closed, stopping flow.
Sealing Mechanism:
The ball valve uses seats around the ball's bore and a floating or spring-loaded seat design
to ensure tight sealing when closed.
Materials:
Available in various materials including brass, stainless steel, bronze, PVC, and other
plastics, suitable for different applications based on fluid compatibility, pressure, and
temperature requirements.

Applications:
Industrial Processes:
Used in various industries such as oil and gas, chemical processing,
pharmaceuticals, and water treatment for on/off flow control.
Utilities
: Commonly found in water supply systems, HVAC systems, and utilities for
residential and commercial buildings.
High-Pressure Systems:
Suitable for applications requiring high-pressure and
high-temperature resistance.
Corrosive Environments:
Certain materials like stainless steel and PVC make them suitable
for handling corrosive fluids.
