Orbit ball valves also called rising stem ball valves.
Orbit Ball Valve adopts special stem to make the ball rotate after separated from valve seat so that there is no abrasion between ball and seat when operate the valve. Therefore the orbit ball valve has much lower operate torque and longer service life.
The orbit ball valve is suitable for harsh service containing solid particle, sand, short fiber, pulp, slurry etc. and high speed fluid which erode the ball and seat hardly.
The orbit ball valve also adopts top entry design to make the maintenance can be made online without dismantling from the pipeline.
