Product Description

Introduction
Eccentric segment half-ball valve is a kind of new developed ball valve which is specialized in solving the technical problem of "solid-gas" and "liquid-gas" fluids medium conveying. It is mainly used for cutting off, regulating or changing the direction of medium in the pipeline. Eccentric segment half-ball valve is widely used in steel mill alumina plant , soda ash plant ,water works and so on.

Characteristics of Henan Quanshun Brand segment half-ball valve
 
1.Advanced design concepts and methods make the valve has the advantages of small flow resistance coefficient & low energy consumption.
 
According to the analysis through mathematical model of fluid motion Bernoulli equation, momentum equation, continuity equation, energy conservation law, our development and research team analyse the imitative flow pattern by ANSYS software ,then design and optimize the valve body with Solid works, which ensure the valve body to be full size design and the fluid resistance coefficient is close to zero.

2.  Due to unique double eccentric structure, the segment half-ball valve can cut solid particles, has "self-cleaning" effect.
 
The segment half-ball adopts eccentric structure, when the hemisphere opens about 8°from the closed position, the hemispherical sealing surface almost completely separates from the valve seat sealing surface, thereby reduces wear between the valve seat and valve disc sealing when it opens and closes. When the valve disc is closed, the force between the valve disc and valve seat sealing surface can effectively cut off the solid particles on the sealing surface of the valve disc, therefore, the segment half-ball valve has a good self-cleaning effect on the sealing surface. Following is our test on shear force during the valve is opening and closing, the shear force can cut off steel wire, and the cross-section is still smooth after the paper test . 

3.  Combined with a variety of wear-resistant material, the hardening treatment of the valve materials makes sealing performance better. We can also spray the inner valve body and valve disc for serious conditions ,and the hardness is no less than HRC 60.
 
4. High sealing performance
   For the valve ball, we machined the valve ball by CNC and grinding it to get high precision. When the valve is sealed, the leakage can reach to class VI .
