Compact Pneumatic O Type Three Way Ball Valve 15-200mm Nominal Diameter
ZSQRJ Compact Pneumatic Three-Way O-Type Ball Valve
The standard ball core of the ZSQRJ compact pneumatic three-way ball valve has L-type three-way double-port channels and T-type three-port channels. By changing the relative angle between the ball core and the pipeline, different combination controls of fluids in the three branch pipes can be realized. The T-type channel can connect three orthogonal pipelines to each other, or connect two of the pipelines while cutting off the other. The L-type channel can only connect two mutually orthogonal pipelines or switch directions. That is, the T-type channel plays the role of splitting and converging, and the L-type channel plays the role of distribution. The three-way O-type ball valve is equipped with a double-acting or single-acting RC pneumatic piston actuator (large-caliber ones are equipped with ZSH horizontally installed piston actuators).
