ABSTRACT:
There is described a solenoid pilot operated change-over valve of the type using a spool/piston assembly which is movable in response to pressure prevailing in a pilot chamber, wherein the effective diameter of a drain valve seat in the pilot chamber is formed at least 1.4 times greater than that of a pilot valve seat on the piston through which the pilot chamber is communicable with an input port of the valve. The spool/piston assembly is reset to the initial position upon de-energization of the solenoid before the pilot valve seat is completely closed by a plunger.
