トエアー式スプール弁。 A switching valve that controls the supply of working fluid to drive a dual diaphragm pump, which has diaphragm pumps on both sides that are driven by working fluid pressure and alternately performs suction and discharge. A spool valve that alternately switches air passages by means of a piston that receives pressure at both ends of the spool, and a pilot that prevents neutralization by providing a magnet on at least one of the end surfaces in the cylinder corresponding to the pressure receiving surface of the piston. Air operated spool valve.
