<p>A plurality of valve assemblies (10) are provided to a base (11), and an air-supply flow path for supplying compressed air to each valve assembly is formed in the base. A main flow path communicating with the air-supply flow path (21) and communicating with a pilot air-supply flow path (44) is formed in an air supply block. When the compressed air is supplied to the air-supply flow path and the pilot air-supply flow path from the main flow path, a manifold solenoid valve becomes an internal pilot type. An external pilot flow path communicating with the pilot air-supply flow path is formed in an external pilot block, and when the external pilot block is provided, communication between the main flow path and the pilot air-supply flow path is shut off, and the manifold solenoid valve becomes an external pilot type in which the pilot pressure is supplied from the external pilot flow path.</p> |
