Solenoid valve and manifold assembly

A solenoid valve and manifold assembly, comprising a manifold body, a solenoid pilot change-over valve placed on said manifold body and including a change-over valve having a valve body and a solenoid pilot valve provided on said valve body for controlling said change-over valve, said manifold body having at least a supply path and an external pilot path formed therein, said valve body having formed therein at least an inlet port and a pilot port which is communicated with said solenoid pilot valve, and a gasket capable of being disposed between said manifold body and said valve body alternatively in first orientation or in second orientation reverse to the first orientation and having at least a supply hole, an internal pilot hole and an external pilot hole formed therein such that an exit of said supply path of said manifold body is communicated with said inlet port of said valve body by way of said supply hole whether said gasket is disposed between said manifold body and said valve body in the first orientation or in the second orientation;

• said exit of said supply path is communicated with said pilot port by way of said internal pilot hole when said gasket is disposed in the first orientation, but when said gasket is disposed in the second orientation, said internal pilot hole is displaced from said exit of said supply path and said pilot port;
• and said external pilot hole is displaced from said pilot port and an exit of said external pilot path when said gasket is disposed in the first orientation, but when said gasket is disposed in the second orientation, said exit of said external pilot path is communicated with said pilot port by way of said external pilot hole.
