Abstract
A multiple electromagnetic valve includes a main valve portion in which four or more valve holes are formed parallel to each other inside a valve body, and a spool for switching flow paths is placed in each valve hole, and a pilot operating portion having solenoid-operated pilot valves that drive the spools with pilot fluid. The valve holes are disposed inside the valve body in two upper and lower tiers. A plurality of valve holes belongs in each of the upper tier and lower tier. The valve holes in the upper tier and the valve holes in the lower tier occupy different positions in the width direction of the valve body. The valve holes in the upper tier and the valve holes in the lower tier partially overlap each other in the plan view of the valve body.
