PP Hollow Balls are made of polypropylene as the main material and have the following core features:
Smooth surface and no intermediate mold line: The smooth surface and no mold line design ensure a tight fit between the ball and the sealing component, reducing the risk of leakage.
Lightweight Design: The hollow structure makes it light, reducing the burden on the valve drive components.
Chemical corrosion resistance: Polypropylene material has good corrosion resistance and can be used for a long time in harsh environments in chemical, pharmaceutical and other fields.
High temperature resistance and wear resistance: PP Hollow Balls have high thermal stability and mechanical strength, and can maintain stable performance under high pressure and high frequency operation.
Key performance in sealing valves
The notable performance of PP Hollow Balls in sealing valves is their sealing performance. The smooth surface without any intermediate mold lines not only eliminates the surface cracks and gaps that may exist in traditional spheres, but also enables high-precision matching with sealing components.
When the sealing valve is working, PP Hollow Balls usually need to maintain dynamic contact with the seal in the valve body. If the ball surface is rough or has mold lines, the friction will increase significantly, which will not only affect the flexibility of valve operation, but may also cause premature damage to the seal. The smooth surface design of PP Hollow Balls effectively reduces friction, extending the service life of valves and seals while ensuring smooth valve operation.
In fluid control, the accuracy of sealing valves is critical to system performance. PP Hollow Balls have high dimensional accuracy, uniform surface, and mold line-free design to ensure stable movement trajectory in the valve.
The corrosion resistance and high temperature resistance of PP Hollow Balls make them adaptable to a variety of harsh working environments. In the chemical industry, it can resist the erosion of acid and alkali liquids; in high-temperature steam valves, it can maintain dimensional stability and is not easily deformed.
Typical application scenarios
Valves in the chemical industry are often exposed to highly corrosive media. The corrosion resistance of PP Hollow Balls ensures that they can work in hydrochloric acid, sulfuric acid and other media for a long time without being corroded. At the same time, the smooth mold-free surface effectively reduces the wear of the seals. , extending the service life of the valve.
In food processing and pharmaceutical production, sealing valves need to meet high hygiene standards. The smooth surface of PP Hollow Balls not only facilitates cleaning, but also avoids the residue of contaminants in the medium, ensuring the safety and reliability of the production process.
In high temperature and high pressure valves, the high temperature resistance of PP Hollow Balls can effectively cope with conditions and ensure stable sealing performance. Its lightweight design also reduces the energy demand on the drive device and improves the overall efficiency of the system.
In order to meet the high performance requirements of sealing valves, PP Hollow Balls are produced using advanced injection molding technology and strict quality control measures:
Precision mold manufacturing: Ensure that the dimensional accuracy and surface smoothness of each sphere meet the requirements.
Polymer material modification: Improve the wear resistance and mechanical strength of polypropylene, making it perform better in high-pressure sealing applications.
Comprehensive quality inspection: Each sphere must undergo strict inspections on surface finish, dimensional consistency and compressive resistance before leaving the factory to ensure that the product meets the stringent requirements of various industries.
