The top-mounted eccentric hemisphere valve adopts advanced sealing technology to ensure excellent sealing performance under various working conditions and effectively avoid leakage phenomenon. Its all-pass design enables the fluid to flow smoothly, reducing pressure loss, thus improving the efficiency of the whole system. In addition, the valve is made of high quality materials and precision processed to ensure wear and corrosion resistance, thus extending their service life.
● Its structure adopts the principle of eccentric wedge to realize the purpose of adjusting and closing through the transmission mechanism: the sealing pair is a metal surface ring with a hard contact seal. When the double eccentric structure is located in the ball storage chamber, the flow section is large and the valve is not washed. When closed, the spool is not washed off. When opening, the valve core sphere gradually moves along the valve seat, effectively eliminating scaling obstacles and realizing reliable seal.
● The hemisphere of the valve: made of bimetallic with different alloys deposited on the substrate. The valve seat also has the corresponding surface and special treatment. The sealing surface group is composed of various types, such as corrosion prevention, wear resistance, high strength and so on, to meet the needs of different occasions
● Seal: zero leakage of conveying harmful gas
● Seal the pair of the remaining compensation: when the valve wear, turn a little more, can be reliably sealed, prolong its service life
