Eccentric hemisphere valve
Product Features of Eccentric Hemisphere Valve
More reasonable structure design
Adopting the eccentric - deed principle achieves the purpose of the brake tightly, regulation by transmission mechanism. The sealing ring surface is metal with hard faced contact seal. Double eccentric structure is in the open when the valve core is located in the ball room.large flow area and zero water loss, can save a lot of resources, and the valve is not washed.close the valve core will not be washed,and open the valve core sphere can effectively move along the seat, so as to easily remove fouling obstacles, achieve reliable seal,and the two-phase mixed flow easily scale solid precipitation mixed flow convey particularly effectively.
Lower pressure loss
Fully open when the water loss is zero, the flow channel is completely smooth; chest automatic cleaning.,The valve core is can rotate in 90 angle, automatically flush valve chest and clean up the debris of the medium.)Also,the debris will not be deposited in the valve chest.The ball is hemispherical. Circulation with the highest Cv value enhanced the system efficiency of the pump and the abrasion is reduced to the lowest degree.
Better quality assurance of sealing
Using eccentric principle, the ball and valve seat are closed tightly under the positive pressure, so as to obtain good sealing; floating seat under the anti pressure, will push the ball towards valve seat. The higher the pressure, the closer between valve seat and the ball, So that the sealing can get a good automatic seal function.
Longer service life
No wearing parts. Due to the eccentric effect, in the process of opening and closing, the valve body completely separated from the sealing of valve seat, and make the seat surface and the spherical cap shift without friction between spherical rotation.At the same time it can reduce operating torque effectively and operate easily.
