A rotary manifold in which the piping ports are aligned in a spiral pattern for easy piping. [Features]· Stable rotational torque that is not easily affected by supply pressure or temperature fluctuations.· There is no change in the rotary torque due to spool sticking to the rotating surface, even after a long periods of non-operation.· Low rotational torque: 0.003 to 0.50 N·m or less.· Operating temperature: -10 to +80°C.· Allowable rotational speed: 200 to 3,000 min-1 (rpm). [Applications]· For air supplies to rotational/rocking shafts on metal-seal type turntables, robot arms, etc.
