A pneumatic stainless steel ball valve is a type of industrial valve designed for controlling the flow of fluids or gases in a piping system. It consists of a stainless steel housing with a spherical ball inside that has a hole through its center. When the valve is in the open position, the hole aligns with the flow path, allowing fluid or gas to pass through. When the valve is closed, the ball is rotated 90 degrees to block the flow path, preventing the passage of fluid or gas.
The pneumatic aspect of the valve refers to its actuation mechanism. Instead of manual operation, pneumatic stainless steel ball valves are operated using compressed air or gas. A pneumatic actuator is attached to the valve, which uses air pressure to control the opening and closing of the valve. This pneumatic actuation allows for remote operation, automation, and precise control of the valve position.
Although there are numerous parts making up the valve the basic components are made up of the following:
Also referred to as the valve housing or shell, it contains all the inner components of the valve. Usually composed of a rigid metal, in this case Stainless Steel, it protects all the internal components and keeps them in the correct position and aligned for proper functioning. It also facilitated access for the external handle to connect with and rotate the internal ball, via the stem. The valve body comes in three assembly options: one-piece, two piece and three-piece designs.
This is the part that gave the valve its name. It is a ball that has "flow path" known as a bore, through the center that allows the medium to flow through it. The ball is rotated by the stem, which either opens the flow when the bore is in-line with the pipe or closes the flow when the bore is perpendicular to the flow. There are two types of bore design: Full port and Reduced port.
Also referred to as the shaft, it connects the external handle that rotates the inner ball. The Stem has washers and packing rings to ensure a tight seal and to prevent any leaks. The stem is rotated as the handle is turned, which in turn rotates the ball, opening and closing the flow.
The Seat sits between the ball and the valve body and ensures a water tight seal. There are two seats that sit on either side of the ball and are usually composed of (PTFE).
The handle is also often called the lever. it a standard ball valve it is the manual way used to turn the ball valve to the open or closed position.
