Ball Valve
A ball valve is a quarter-turn, shut-off valve that uses a hollow, rotating ball to control the flow of a gas or liquid. When the valve is open, the hole in the ball aligns with the pipe, allowing fluid to pass through. When the valve is closed, the ball is rotated 90 degrees so the hole is perpendicular to the flow path, creating a leak-tight seal.
Operational Features
-
Quarter-Turn Operation
Ball valves can be fully opened or closed with a simple 90-degree turn of the handle, allowing for quick and easy operation.
-
Tight Shut-Off
The design provides excellent sealing capabilities, ensuring zero or minimal leakage when closed.
-
Straight-Through Flow
When fully open, the ball allows for a direct, unobstructed flow path, resulting in minimal resistance and a low pressure drop.
Durability & Versatility
-
Robust Construction
Ball valves are durable and can be constructed from various materials like stainless steel, brass, or plastic, allowing them to handle high pressures and temperatures.
-
Media Versatility
They are suitable for controlling a wide range of fluids, including clean liquids, gases, and even liquids with suspended solids (slurries).
-
Multi-Port Design
Some ball valves can be designed with multiple ports, reducing the need for additional valves and offering increased flow control options.
Safety & Specific Features
-
Blow-Out Proof Stem
This design prevents the stem from being ejected under high internal pressure, enhancing safety.
-
Antistatic Feature
This feature helps dissipate static electricity, which is important when handling potentially flammable materials.
-
Firesafe Design
Some ball valves are designed to remain functional and provide a seal even after exposure to a fire.
