Track Ball Valve
In order to meet the market demand, Lianda has developed the orbit ball valve by introducing and absorbing foreign advanced technology and improving it. Its working principle is to use the principle of the cam to make the sphere in the process of rotation and the valve seat sealing surface of the separation, rotation in place and then push the sphere to the valve seat to achieve sealing. Compared with the conventional ball valve, the rail ball valve has been used in many working conditions due to its advantages of no friction, light valve torque and good sealing performance.

Structural Characteristics
Instructions
Hardening of the stem guide groove
when the stem switch, the guide groove will be subjected to a large load. Therefore, the guide groove needs to do the corresponding hardening treatment.
Double stem guide pin
The hard stem guide groove and the stem guide pin cooperate with each other to lift and rotate the stem.
Filler loading sealing
the packing place adopts the disc spring loading design, and the long-term sealing is more reliable
Top type design
simplify the maintenance.
Prevent leakage
the top assembly structure has less leakage points, the valve body valve cover is sealed with metal sealing ring, good sealing, and has fire prevention function.
Single valve seat design
can realize the two-way sealing without closed middle cavity, to avoid the problems of middle cavity pressure and middle cavity cup.
Switch without friction
because the rail ball valve sealing surface switch without friction, rotation is particularly easy, the service life is much greater than the conventional valve.
Hard sealing surface of anti-wear valve core
according to different working conditions, the surface of the valve core is suitable for supersonic spray welding, which can meet the application in very demanding occasions.
Mechanical wedge seal
The inclined plane at the lower end of the stem provides a mechanical wedge tightening force to ensure continuous tight sealing.
