Features

1. Its structure adopts the eccentric tightening principle to achieve the purpose of gate tightening, adjustment and closing through the transmission mechanism. The sealing pair is a metal surface ring with a hard surface contact seal. When the double eccentric structure is opened, the valve core is located in the ball chamber, and the flow cross-section is large. , and the valve will not be washed, the valve core will not be washed when closed, and the spherical surface of the valve core will gradually move along the valve seat when opened, effectively removing scaling obstacles and achieving reliable sealing. It is particularly effective for mixed flow transportation of two-phase mixed flow where solids that are prone to scaling are precipitated.

2. The hemisphere of the valve is made of bimetal, and different alloys are overlayed on the base metal. The valve seat is also overlayed accordingly and undergoes special treatment. The sealing surface is combined into various types such as anti-corrosion, wear-resistant, and high-strength to meet the needs of different occasions.

3. It is tightly sealed and can transport harmful gases with zero leakage.

4. There is a compensation amount left in the valve core of the sealing pair. When the valve is worn, rotate it a little when closing to ensure reliable sealing and extend the service life. In addition, the user can unscrew the compression nut and the valve seat can still be used after adjustment or replacement, thus avoiding the disadvantage of scrapping the entire unit after the valve seal fails.

5. The structure of the top-mounted eccentric semi-ball valve has a cover on it, which can be repaired on the pipeline, which is convenient and labor-saving.
