DYQ940 Electric Eccentric Hemisphere Valve Product Application

The products are divided into seven series according to their uses: general valves, pipeline valves, sewage valves, slurry valves, gas valves, petrochemical valves, and coal powder injection valves. In industries such as petroleum, gas, metallurgy, ash discharge, chemical, power, and coal powder injection, it is an upgraded product of gate valves, globe valves, Y-shaped valves, and ball valves.

The emergence of DYQ940 electric eccentric hemispherical valve marks a new stage in ball valve technology. One of the characteristics is that the sealing surface can achieve self-cleaning. When the ball leaves the valve seat, the medium can flush away the accumulated substances on the sealing surface. For easily crystallized media, the ball can cut off the medium crystallization during the closing process to achieve the sealing purpose, avoiding the disadvantage of other valves being unable to open and close; When the ball leaves the sealed position during opening, it completely disengages, and the opening torque is small; The second characteristic is that there is no friction in opening and closing. Due to the use of an eccentric structure, during the closing process of the valve, the ball gradually approaches the valve seat and fully contacts the closed position; The third characteristic is that when the seal is worn out after a long period of use, only the compression sleeve needs to be tightened slightly when closing, which can still achieve reliable sealing and extend the service life. In addition, by adjusting or replacing the seals, the valve can continue to be used, avoiding the drawbacks of many valve seals failing and being scrapped as a whole.
The fourth characteristic is tight sealing. The ball and valve seat are made of bimetallic materials, and different processes are adopted. The sealing surface can be combined into various types such as anti-corrosion and wear-resistant to meet the needs of different working conditions. The sealing is achieved by spherical linear contact and zero leakage through two-dimensional eccentricity.
