<p>PROBLEM TO BE SOLVED: To provide a pilot type switching valve wherein passage taking is facilitated of a pilot passage for switching an internal/external pilot type further with a switching mechanism provided by reducing a cost. SOLUTION: In this switching valve, a pilot input passage 23 communicating with an inlet port of a pilot valve 3, internal pilot passage 21 communicating with a supply port P, and an external pilot passage 22 communicating with an external pilot port X, are opened adjacent to an upper surface of a main valve 2. In an opening part of these pilot passages, a switching plate 26 is mounted, which has a switching passage 27, by changing a mounting attitude to the main valve 2, switching the pilot input passage 23 to the internal/external pilot passage 21, 22 so as to be communicated.</p> |
