Eccentric Semi ball valve side entry

Eccentric Semi ball valve side entry introduction
Eccentric Semi ball valve side entry internal structure is one piece, the internal parts from the side of the installation and disassembly of a valve.Eccentric Semi ball valve side entry adopts eccentric body, eccentric ball and seat, the stem rotates in the common trajectory automatic centering, the closing process more and more tight, completely achieve a good sealing purpose.Eccentric Semi ball valve side entry ball and seat are completely separated, eliminating the wear of the sealing ring and overcoming the problem of the traditional ball seat and ball sealing surface wear all the time. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the seat is well protected.Eccentric Semi ball valve side entry is especially suitable for steel industry, aluminum, fiber, micro solid particles, pulp, coal ash, LPG and other media.

Eccentric Semi ball valve side entry structure feature
1. Open and close without friction.
    This function completely solves the problem of traditional valve sealing due to friction between sealing surfaces.
2. Top entry structure.
    The Side entry eccentric half ball valve installed on the pipeline can be directly inspected and maintained online, which can effectively reduce device shutdown and cost.
3. Single seat design.
    The problem of abnormal pressure boost in the medium of the Side entry eccentric half ball valve affecting the safety of operation is eliminated.
4. Low torque design.
   Specially designed stem can be opened and closed with a small hand handle.
5. Wedge sealing structure.
   Side entry eccentric half ball valve is provided by the stem of the mechanical force, the ball wedge pressure on the seat and sealing, so that the valve sealing is not affected by the pipeline differential pressure changes, sealing performance in various working conditions are reliable guarantee.
6. Self-cleaning structure of sealing surface.
    When the ball leans away from the seat, the fluid in the pipeline passes through the ball sealing surface in a 360° uniform way, which not only eliminates the local flushing of high-speed fluid on the seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
