Abstract
A spherical valve member is moved within a housing between operative positions by direct application of supply pressure and operation of a solenoid arranged to maximize mechanical force imposed on the valve member while minimizing solenoid size and eliminating the use of movable close fitting cylindrical parts which can be subject to sticking in the presence of solid contaminants.
