Kuulventiile

Kuulventiile, also known as ball valves, are a type of quarter-turn valve used to control or isolate flow in a pipeline. They operate by rotating a hollow, perforated ball situated within the valve body. When the hole is aligned with the flow path, the valve is open, allowing fluid to pass through. When the ball is rotated 90 degrees, the hole becomes perpendicular to the flow, blocking the passage and closing the valve.

These valves are characterized by their simple design and reliable operation. They offer quick shut-off capabilities, making them suitable for applications requiring frequent operation. Kuulventiile are known for their tight sealing, which minimizes leakage when the valve is closed. They can handle a wide range of pressures and temperatures, and are compatible with various media, including liquids, gases, and slurries.

The construction of a kuulventiili typically includes a valve body, a ball, a stem, seats, and a handle or actuator. The ball is usually made of metal or plastic, while the seats are often made of resilient materials like PTFE or rubber to ensure a good seal. The stem connects the ball to the external operating mechanism, allowing for rotation.

Kuulventiile find widespread use in numerous industries, including oil and gas, chemical processing, water treatment, and HVAC systems. They are employed in applications such as flow control, on-off isolation, and emergency shut-down. Their versatility and effectiveness have made them a common choice for many industrial and commercial fluid handling needs.
