A stainless steel ball valve is a type of valve that utilizes a stainless steel ball to control the flow of fluids through a pipeline. It's one of the most common types of ball valves due to stainless steel's excellent corrosion resistance, durability, and suitability for a wide range of applications, including water, oil, gas, and various chemicals.
Two-Way or Multiport Configurations: Stainless steel ball valves can be configured for two-way flow (on-off control) or multiport designs for diverting flow in different directions.
Manual or Automated Operation: They can be operated manually using a handle or lever for simple on-off control, or they can be automated using actuators (such as pneumatic, electric, or hydraulic actuators) for remote operation and precise flow control.
Quarter-Turn Operation: Stainless steel ball valves typically operate on a quarter-turn mechanism. When the handle is turned 90 degrees, the ball rotates within the valve body, either opening or closing the flow passage.
Sealing Mechanism: Stainless steel ball valves may feature various sealing mechanisms, including resilient seats made of materials like PTFE or metal-to-metal seals, depending on the application requirements and operating conditions.
Operation:
Open Position: When the handle is turned or lever is actuated to the open position, the ball rotates 90 degrees, aligning the hole in the ball with the inlet and outlet ports. This creates an unobstructed flow path, allowing fluid to pass through the valve.
Closed Position: When the handle is turned or lever is actuated to the closed position, the ball rotates back 90 degrees, perpendicular to the flow path. This blocks the flow of fluid by closing off the inlet and outlet ports with the solid part of the ball, effectively sealing the valve shut.
Quarter-Turn Operation: Stainless steel ball valves typically operate on a quarter-turn mechanism, meaning that the valve only needs to be turned 90 degrees from fully open to fully closed or vice versa. This makes them quick and easy to operate.
Stainless steel ball valves work on a simple yet effective principle to control the flow of fluids through a pipeline. Here's how they typically operate:
Valve Body: The valve body of a stainless steel ball valve is a hollow structure with inlet and outlet ports that are connected to the pipeline. It is usually made of stainless steel for corrosion resistance and durability.
Ball: Inside the valve body, there is a spherical or ball-shaped component, typically made of stainless steel as well. This ball has a hole or bore drilled through its center that aligns with the inlet and outlet ports when the valve is in the open position.
Handle/Lever: On the outside of the valve body, there is a handle or lever mechanism attached to the top of the ball. This handle is used to manually rotate the ball within the valve body.
Sealing Mechanism: The valve typically has seats or seals located on both ends of the valve body. These seals ensure a tight closure when the valve is in the closed position, preventing leakage of fluid.
