Abstract

A solenoid valve and manifold assembly wherein a solenoid pilot change-over valve can be selectively used as of the internal pilot type or as of external pilot type. The manifold comprises a gasket capable of being disposed between a manifold body and a valve body of a change-over valve of the solenoid pilot change-over valve alternatively in first or reverse second orientation and having a supply hole, an internal pilot hole and an external pilot hole formed therein. The supply path is communicated with an inlet port of the valve body by way of the supply hole whether the gasket is disposed in the first or second orientation. When the gasket is disposed in the first orientation, the supply path is communicated with a pilot port of the valve body by way of the internal pilot hole while the external pilot hole is displaced from the pilot port and an external pilot path of the manifold body, but when the gasket is disposed in the second orientation, the internal pilot hole is displaced from the supply path and the pilot port while the external pilot path is communicated with the pilot port by way of the external pilot hole.
