Features
1.This valve features a double-eccentric structure, ensuring a tighter seal as it closes, with reliable sealing performance.
2.The sealing pair materials are stainless steel and oil-resistant nitrile rubber, offering a long service life.
3.The rubber sealing ring can be located on either the valve body or the disc, making it adaptable to different media characteristics for user selection.
4.The disc uses a frame structure, providing high strength, large flow area, and low flow resistance.
5.The overall baking finish effectively prevents corrosion. By replacing the sealing material of the valve seat, it can be used with different media.
6.This valve has bidirectional sealing capabilities, allowing installation without being restricted by media flow direction or spatial position. It can be installed in any orientation.
7.The valve has a unique structure, with flexible, labor-saving, and convenient operation.
