PURPOSE:To decrease a number of valve ports and passages in a valve and facilitate its manufacture as compared with the valve using two pilot solenoid operated valves of three-port valve construction, by using two pilot solenoid operated valves of two-port valve construction to control a spool to be slided. CONSTITUTION:A solenoid operated valve case 15, in which two right and left pilot solenoid operated valves 13, 14 are built in a reverse direction to each other, is additionally provided in the right side outer end of a valve main unit 1. Each pilot solenoid operated valve 13, 14, both slidably fitting a plunger 16 to be mounted in a guide cylinder 17 and urging the plunger 16 by a spring 18 to the outside of the guide cylinder 17, winds a solenoid 19 to be attached to the periphery of the guide cylinder 17. In this way, electric wiring with the outside can be arranged only in one side of the valve main unit 1 because the both pilot solenoid operated valves 13, 14 are built in the common solenoid operated valve case 15 in one end of the valve main unit 1. |
