To ensure smooth and flexible operation of the valve stem over a prolonged period, it is crucial to reduce the friction torque of the stem. This can be achieved by utilizing a highly effective thrust bearing, which minimizes wear and tear and promotes longevity. By reducing friction, the thrust bearing enables the valve stem to operate with ease and efficiency, making it a reliable and durable component of the valve system.
The valve body, valve stem, and ball are equipped with a spring to prevent the buildup of static electricity during the switching process. This anti-static function allows the static electricity generated to be released effectively.
Thanks to the excellent self-lubricating properties of PTFE and other materials, the pneumatic ball valve experiences minimal friction loss when in use. This means that the valve can last for years without wearing out quickly, providing long-term reliability and stability.
The category of valves that boasts the smallest fluid resistance is the pneumatic ball valve. It outperforms all other valve categories in this aspect. Even when considering the reduced-diameter version of the pneumatic ball valve, its fluid resistance remains remarkably low.
The reliability of the valve stem seal is remarkable due to its rotational movement and minimal vertical motion. This design characteristic contributes to the durability of the packing seal, making it less susceptible to damage. Additionally, as the pressure of the medium increases, the sealing ability of the valve stem seal improves significantly.
The sealing performance of the valve seat is excellent as it is equipped with a sealing ring made of elastic materials such as PTFE. The structure of the valve allows for easy sealing, and as the pressure of the medium increases, the pneumatic ball valve exhibits an enhanced sealing ability.
The full-bore ball valve exhibits almost negligible fluid resistance, resulting in minimal flow obstruction.
8. Simple structure, small size and light weight.
The ball valve is known for its tightness and reliability. With two sealing surfaces, it ensures a secure seal. The sealing surface materials used in this valve are extensively found in various plastics, providing exceptional sealing performance and enabling complete sealing. Due to its excellent sealing capabilities, the ball valve has gained popularity in vacuum systems.
This device is very user-friendly, allowing for easy operation and quick opening and closing. To fully open or close it, you only need to rotate it 90°, which is incredibly convenient for remote control over long distances.
The ball valve has a simple structure, making it easy to maintain. It is also convenient to disassemble and replace because the sealing ring is generally movable.
The ball valve's sealing surfaces remain isolated from the medium when it's fully opened or fully closed, which prevents any erosion of the valve sealing surface while the medium passes through.
Flexible in their applications, these tools can be used across a wide range of industries and scenarios. They come in various sizes, spanning from tiny dimensions of just a few millimeters to significantly larger ones measuring several meters in diameter. Moreover, their versatility is demonstrated by their ability to function effectively in extreme environmental conditions, from high vacuum environments to high-pressure settings.
The ball valve is instrumental in handling mediums that contain suspended solids as it has a wiping property while opening and closing, which prevents build-up around the valve.
The valve in question boasts of exceptional processing accuracy demanding a high price, but it is impractical to deploy at high temperatures. It proves vulnerable to blockades in environments where pipeline impurities are present, which sometimes leads to the failure of the valve to open.
