1. The main components of this product, such as the main valve body, auxiliary valve body, and pressure cover, are cast into shape, which has the advantages of light weight and lower cost compared to forged steel valves.

2. Adopting a movable metal valve seat structure with cylindrical or waveform spring preloading, the sealing pre tightening force is designed reasonably and the closing and opening are flexible, effectively ensuring the reliability of the seal.

3. The sphere is made of ultra fast spray wear-resistant alloy powder material, and the valve seat is also treated with overlay welding of Stellite hard alloy and spray coating of other ultra wear-resistant alloy materials.

4. The sealing surface is finely polished, ensuring reliable sealing.

5. Full channel design, low flow resistance, and high flow capacity.

6. The anti flying design of the valve stem is safe and reliable, and anti-static functions can be designed according to requirements.

7. Automatic pressure relief valve seat design, once the cavity in the valve body abnormally increases pressure, the valve seat will automatically release towards the lower pressure end, making it safer.

8. Both the upper and lower valve stems are designed with bearing structures, providing lighter torque during opening and closing.

9. Multiple driving modes to choose from: manual, worm gear transmission, pneumatic, electric, hydraulic, gas-liquid linkage, etc; It can also be used in conjunction with transportation control automation.
