Steel Ball Valve ASME B16.34 FBAV-20
Steel ball valves are valves that contain a ball with a hole in the center. A 90° rotation of the ball allows the valve to transition from fully open to fully closed. These valves are preferred in systems that open and close frequently or require rapid opening and closing. Steel ball valves, offered by ORFA Industrial Products Industry and Trade Inc. , stand out for their low pressure loss, ease of opening and closing, light weight, and compact design. Valve leakage is achieved in two stages: ball sealing and stem sealing.

Steel Ball Valve Working Principle
Steel ball valves are frequently used in fluid control and are highly efficient. Their basic operating principle is to control fluid flow by rotating a sphere with a hole in the center. Here's an article detailing the operation of steel ball valves:
1. Structural Features and Working Mechanism
Steel ball valves typically consist of the following basic components: a stainless steel body, a stainless steel sphere, and a sealing element (seat). The body is the part of the valve's exterior that withstands high pressures. The sphere is the rotating element within the valve, with a hole in the center. The sealing element ensures a tight seal between the sphere and the valve body.
The operating principle of a ball valve is based on a 90° rotation of the ball. This rotation allows the valve to transition from fully open to fully closed. The ball is rotated via a shaft called the spindle, which can be moved manually or by actuators.
2. Flow Control
When the valve is in the open position, the hole in the center of the sphere aligns with the pipeline, allowing fluid to flow freely. This ensures fluid flow with minimal pressure loss. When the sphere is parallel to the pipeline, the valve is open.
In the closed position, the valve is rotated 90°, bringing the center hole into a position perpendicular to the pipeline. This completely blocks fluid flow, stopping it from flowing. When the valve is perpendicular to the pipeline, the valve is closed.
3. Sealing
Sealing of steel ball valves is achieved in two main areas: ball sealing and stem sealing. The contact between the ball and the sealing elements (seat) prevents fluid leakage. This contact ensures a high seal even when the ball rotates. Stem sealing, on the other hand, occurs where the stem enters the valve body. Seals used in this area prevent fluid leakage around the stem.
4. Pressure and Flow Control
Steel ball valves adapt to the fluid pressure. When the medium pressure is low, the contact area between the sealing ring and the ball is small, resulting in greater sealing pressure. When the medium pressure is high, the contact area increases, allowing the sealing ring to withstand greater pressure. Sealing elements made of materials such as RPTFE provide low friction loss thanks to their self-lubricating properties, contributing to the valve's longevity.
Areas of Use
Steel ball valves have a wide range of uses and are particularly preferred in the following sectors:
Food Industry: Used in areas such as milk and dairy production facilities, liquid oil production facilities, and beverage production facilities. The valves' leak-tightness and hygienic structure make them ideal for the food industry.
Paper Manufacturing Plants: Used to meet flow control and sealing requirements in paper manufacturing processes.
Chemical and Petrochemical Industry: Widely used in oil, fuel, natural gas, and chemical production facilities. Its chemical-resistant structure offers a reliable solution in this sector.
Natural Gas Lines: Used for the safe and controlled transmission of natural gas.
