PURPOSE:To dispense with precise finishing work of components by arranging a valve body which accomodates a spool and a valve seat, in a composition of two divid halves, in such a way as combining one valve body half with the other half, while adjusting the position of a valve seat during visual recognition of the relative position between these halves. CONSTITUTION:When two valve body halves 10a, 10b are combined, an inflow pipe 20 is pressed into a port P, located in a central position of a valve hole half 12a of one valve body half 10a, and an internal valve seat block 17 is fixed to the valve body half 10a. Subsequently, the position of a spool 15 in the valve hole half 12a of an external valve seat block 18 is adjusted. Then, the valve body half 10a is combined fluid-tight with the other valve body half 10b by means of a bolt and the like through a packing 22, while an end board 13 is connected fluid tight to one end of a valve body 10 through a packing 22, and further an electromagnet 11 is connected to the other end. |
