ノイドバルブ。[Scope of Claim for Utility Model Registration] A spool that is slidably provided in a valve body and switches input and output ports on and off, a pilot fluid chamber formed at one end of the spool, and a plunger in a first position. When the plunger is switched to the second position, the pilot fluid pressure is cut off from the pilot fluid chamber and communicated with the drain port, and when the plunger is switched to the second position, the pilot fluid chamber is cut off from the drain port and at the same time, the pilot fluid pressure is supplied. A pilot hydraulic pressure switching mechanism and a plunger of the pilot hydraulic pressure switching mechanism are opposed to the magnetic pole surface via a return spring, and when the electromagnetic coil is not energized, the return spring holds the plunger in the first position and the electromagnetic coil is An electromagnetic solenoid valve comprising an electromagnetic solenoid that moves the plunger to the second position when energized, wherein a counterbore is formed in the end face of the plunger facing the magnetic body, and a counterbore is formed in the plunger and a counterbore is provided in the pilot liquid chamber. An electromagnetic solenoid valve characterized by forming a communication path for communicating with a connected liquid chamber.
