| description | To make it easy to mount magnets for monitoring a switched state of a valve element in a solenoid valve and to easily mount magnetometric sensors for sensing an approach of the magnet in a state of excellent water resistance and dustproof property. In a solenoid valve for switching a direction of a flow of pressure fluid by driving the solenoid valve by pilot fluid pressure, ring-shaped magnets 13A and 13B are fitted with small-diameter portions 11a formed at end portions of a valve element 11 and is fixed by press fitting and engaging caps 14A and 14B forming faces to be in contact with pistons 14A and 14B at the valve element ends. A housing chamber 30 is formed outside a valve hole 10a in a valve body 10 and in a position close to the magnets, magnetometric sensors 31A and 31B are housed in the housing chamber 30, and a cover 35 is mounted to the housing chamber 30. A connector 37 for leading out a current-carrying wire to pilot valves 20A and 20B and signal lines from the magnetometric sensors is provided to the cover. |
