Abstract
A manifold valve in which mounting of a magnetometric sensor is easy and wiring is easy and which is easy to handle in maintenance and has a position detecting function is obtained. This valve is formed of a solenoid valve 1, a manifold base 2, and an intermediate block 3 disposed between the solenoid valve 1 and the manifold base 2. The solenoid valve 1 includes a magnet 20 for detecting a position and moving in synchronization with a spool 8 and a depression 22 in which a sensor is to be mounted and which is provided in a position corresponding to the magnet 20. The manifold base 2 includes a first plug 28 to be connected to a controller for controlling the solenoid valve. The intermediate block 3 includes a projecting portion 37 to be fitted in the depression 22, a magnetometric sensor 21 housed in the projecting portion 37, and an insertion hole 43 through which a conductor 44 connecting the magnetometric sensor 21 and the first plug 28 is inserted.
