Palloventtiilit

Palloventtiilit, also known as ball valves, are a type of quarter-turn valve used to control or isolate flow in a pipeline. They operate by a rotating spherical closure mechanism. The sphere has a hole, or port, through the center. When the port is in line with the pipe, the valve is open and allows fluid to pass. When the port is turned 90 degrees by the handle, it is perpendicular to the pipe, and the valve is closed, blocking the flow.

Palloventtiilit are popular for their quick operation, simple design, and tight shut-off capabilities. They can be manufactured from a variety of materials, including brass, stainless steel, cast iron, and plastics, making them suitable for a wide range of applications and fluid types, such as water, oil, gas, and chemicals. Their robust construction contributes to their durability and long service life.

These valves are commonly used in industrial processes, chemical plants, oil and gas facilities, water treatment systems, and residential plumbing. They are effective for both on-off service and, in some designs, for throttling or regulating flow. The handle position clearly indicates whether the valve is open or closed, providing visual confirmation of its status. Maintenance is generally straightforward due to their simple internal design.
