PROBLEM TO BE SOLVED: To provide an electromagnetic valve which is improved in durability by alleviating the eccentric wear of a pilot valve.SOLUTION: A pilot-type electromagnetic valve comprises: a pilot valve 4 which opens and closes a pilot valve hole 22 formed at a main valve 2 having a diaphragm 20 as a main body; a plunger 41 connected with the pilot valve; a guide cylinder 42 into which the plunger is slidably inserted; and a solenoid 5 which is arranged so as to surround the guide cylinder. The pilot-type electromagnetic valve also comprises a turning mechanism 6 which turns the plunger 41 around an axial line of the turning mechanism when the plunger 41 moves to at least one side out of an open direction and a closed direction of the pilot valve 4. |
