Polycrystalline silicon special rotary ball valve

超耐磨旋球阀 is a special valve designed specifically for high wear media, combining a butterfly shaped structure with a ball valve sealing principle, and improving wear resistance through hardening processes and special materials. It is suitable for harsh working conditions containing particles and highly corrosive media. Its core features are as follows:

1、 Core advantages
Excellent wear resistance
The sealing surface is made of tungsten carbide coating, ceramic composite material, or integral chromium molybdenum steel casting, with a surface hardness of HRC 60 or above and a wear life of more than 5 times that of ordinary ball valves. Some models are equipped with a self-cleaning scraper structure to prevent particle accumulation from damaging the sealing surface.
Bidirectional hard seal design
Zero leakage sealing can be achieved under both forward and reverse pressure, especially suitable for scenarios that require bidirectional cutoff such as water pump outlets and recycled water systems. A single valve can replace two ordinary one-way valves.
Compact structure and convenient operation
The butterfly eccentric structure achieves 90 degree rotation opening and closing, reducing the volume by 30% compared to traditional ball valves, making it suitable for high-density installation environments (such as blast furnace systems); Low opening and closing torque, can be paired with manual, pneumatic or electric drive devices.

4、 Industry innovation direction
Material upgrade: Basalt cast stone lining or supersonic spraying technology to enhance erosion resistance.
Structural optimization: Ultra thin design saves installation space, and top mounted maintenance is convenient.
Intelligent control: Integrating electric actuators to achieve precise flow regulation.
Note: When selecting, special attention should be paid to the hardness of the medium particles, peak temperature, and pressure fluctuation parameters to match the sealing material and hardening process.
