Pilot-type solenoid valve has washer mounted to screw and having latching part inclined inside and latched onto side wall of washer latching groove, such that solenoid-valve block is fixed to manifold block on screw

摘要

A seat surface (15) is formed at a position adjacent to a screw coexistence concave part (13) at the upper surface of a solenoid-valve block (10). A washer latching groove (20) is formed at seat surface. A washer (24) is mounted to a screw (11) and has a latching part (25) inclined inside and latched onto side wall of latching groove, such that solenoid-valve block is fixed to a manifold block (16) on screw. The solenoid-valve block is mounted on the upper surface of the manifold block.
