Product Description
Gear Operated Flanged Double Eccentric Top Entry Ball Valve (GADYQ340F/H)
1. Its structure adopts the eccentric wedge principle to achieve the purpose of locking, adjusting, and closing through the transmission mechanism. The sealing pair is a metal face ring with a hard contact seal. The double eccentric structure is located in the ball storage chamber when opening, with a large flow cross-section, and the valve is not washed out. When closing, the valve core is not washed out. When opening, the spherical surface of the valve core gradually moves along the valve seat, effectively removing scaling obstacles and achieving reliable sealing. It is particularly effective for mixed flow transportation where two-phase mixed flow is prone to scaling and solid precipitation
2. The hemisphere of the valve is made of bimetallic material, with different alloys deposited on the base material. The valve seat is also subjected to corresponding surfacing and special treatment. The sealing surface group is composed of various types such as anti-corrosion, wear-resistant, and high-strength, meeting the needs of different occasions
3. Tightly sealed, delivering harmful gases with zero leakage
4. The valve core of the sealing pair has a compensation amount left, and when the valve is worn out, it can be reliably sealed by turning a little more when closed, extending its service life. In addition, users can still use the valve seat after screwing off the compression nut, adjusting or replacing it, avoiding the drawback of scrapping the entire unit after the valve seal fails.
5. The top mounted eccentric hemisphere valve structure has a cover on top, which can be repaired on the pipeline, making it convenient and labor-saving.
