Abstract: A valve unit includes a rotary valve having a predetermined clearance between an inner surface of a main body and a valve element. The magnet coupling includes eight outer peripheral magnets and eight inner peripheral magnets having N-poles and S-poles each on an outer or inner peripheral side. The outer peripheral magnets are disposed such that the N-poles and the S-poles are disposed alternately in a circumferential direction and such that a distance between the central axis and an outer peripheral surface of the outer peripheral magnets is between 90% and 100% of a distance between the central axis and an outer surface of the main body closest to the central axis in a direction perpendicular to the central axis. The inner peripheral magnets are disposed opposite to the outer peripheral magnets such that the N-poles and the S-poles are disposed alternately in the circumferential direction.

Abstract: An electromagnetic valve manifold includes an electromagnetic valve including an output port, a manifold base including an output passage, and a spacer arranged between the manifold base and the electromagnetic valve. The spacer includes a spacer block including a shaft hole and a manual shaft accommodated in the shaft hole. The spacer block includes an output connecting passage that is connected to the shaft hole and connects the output passage and the output port to each other. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows for connection between the output passage and the output port through the output connecting passage, and a second switching position, in which the manual shaft blocks the connection between the output passage and the output port through the output connecting passage.

Abstract: A pulse shot-type flow rate control device including first and second shutoff valves, a tank, a pressure sensor, and a controller is caused to perform two or more processes. In each process, the controller repeats pulse shots of alternately causing the first shutoff valve and the second shutoff valve to open and close, changes a way of the pulse shots based on a pressure difference between the pressure after filling and the pressure after discharge, and controls a volume flow rate. In each process, the controller stores, as an optimal filling time, a filling time when the volume flow rate is controlled to a target flow rate, and opens and closes the first shutoff valve by using the optimal filling time in a first pulse shot in the next process.
