Abstract:
1. A manifold-type solenoid valve, comprising: a main valve section having a spool in a valve hole to which respective switching flow paths for supply, output, and discharge are opened; and a solenoid operating section for driving the spool with an electromagnetic force, the main valve section comprising connecting flow paths for collective supply and/or collective discharge having connecting ports opened on a side surface of a housing, output ports on the housing at a first end surface of one end side in an axial direction of the valve hole, and an external port for connecting an external piping for independent supply or independent discharge at the first end surface of the one end side in the axial direction of the valve hole, in the housing, wherein the output ports are in communication with the valve hole via the switching flow path for output, the connecting flow paths for collective supply and/or collective discharge are connectable with connecting flow paths corresponding to neighboring solenoid valves in a solenoid valve assembly via the connecting ports and are in communication with the valve hole via the switching flow path for supply and the switching flow path for discharge, and the external port is arranged on the first end surface adjacent to the output ports and is directly in communication with the switching flow path for supply or the switching flow path for discharge.
