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.
Material: Stainless steel ball valves are primarily made of stainless steel, with common alloys including 316 stainless steel, 304 stainless steel, and others. The choice of material may depend on factors such as corrosion resistance, temperature resistance, and cost.
End Connections: Stainless steel ball valves can have various end connections to suit different piping systems, including threaded (NPT), socket weld, butt weld, flanged, or compression fittings.
Design Standards: Stainless steel ball valves may conform to various industry standards and specifications, such as API (American Petroleum Institute), ANSI (American National Standards Institute), ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), ISO (International Organization for Standardization), and others.
Sealing Mechanism: Stainless steel ball valves may utilize different sealing mechanisms, such as soft seats (made of materials like PTFE) or metal-to-metal seals, to provide a tight seal and prevent leakage.
Operation: Stainless steel ball valves can be manually operated with a handle or lever for on-off control, or they can be automated with actuators for remote operation and precise flow control.
