Patent ID: 8061379

Claim:
A manifold solenoid valve having a plurality of valve assemblies, each of which has a spool valve shaft and a pilot solenoid valve, the spool valve shaft being movable to a position of causing an air supply port to communicate with an output port and a position of causing the output port to communicate with an exhaust port, the pilot solenoid valve being switched to a position of supplying pilot pressure to the spool valve shaft and a position of stopping supplying the pilot pressure to the spool valve shaft, the manifold solenoid valve comprising: a base on which the valve assemblies are mounted and in which a common air-supply flow path communicating with the air supply port, a common exhaust flow path communicating with the exhaust port, and a common pilot air-supply flow path supplying the pilot pressure to the pilot solenoid valve are formed, the base being detachably connected to a support member; an air supply block in which a main flow path communicating with the air-supply flow path, and an internal pilot flow path communicating with the pilot air-supply flow path are formed, the air supply block being disposed on one side of the base and detachably connected to the support member; and an end block which is disposed on an outer surface side of the air supply block and detachably connected to the support member, and which fixes the base and the air supply block to the support member, wherein the manifold solenoid valve is set to an internal pilot type of supplying the pilot pressure to the pilot air-supply flow path from the main flow path by connecting the end block to the air supply block connected to the base, and the manifold solenoid valve is set to an external pilot type of supplying the pilot pressure to the pilot air-supply flow path from an external pilot flow path formed in an external pilot block, the external pilot flow path communicating with the pilot air-supply flow path, the external pilot block shutting off communication between the pilot air-supply flow path and the main flow path, by adding the external pilot block between the base and the air supply block, or between the air supply block and the end block.
