Abstract

A control valve and an operating method thereof are described. The control valve includes a housing containing a valve body. A first solenoid operably connects to a first lateral end of the valve body and a second solenoid operably connects to a second lateral end of the valve body. A first fluid inlet in the housing receives a first fluid at a first predetermined pressure. A second pressure inlet in the housing receives a second fluid at a second predetermined pressure. The valve body moves between a first position, where the valve body is disposed adjacent to a first lateral side of the housing, and a second position, where the valve body is disposed adjacent to a second lateral side of the housing. In the first position, the second fluid is connected to an outlet, and, in the second position, the first fluid is connected to the outlet.
