Multiplexing control valve

A valve assembly comprising:

• a valve body that defines a bore, wherein the valve body includes at least a first port, a second port, and a third port in communication with the bore;
• a valve slidably disposed within the bore and moveable between at least a first position and a second position, the valve having a body and at least one land disposed on the body, wherein the body is coaxial to the bore and defines a fluid passage that communicates with a first opening in the body, wherein the land includes an outer surface sealable against the valve body, and wherein the land defines a radial fluid passage in communication with the fluid passage and with a second opening disposed on the land;
• a biasing member disposed within the bore of the valve body, the biasing member in contact with the valve and operable to bias the valve to one of the first and second positions;
• and
• a control device operatively associated with the valve, the control device operable to move the valve to at least one of the first and second positions against the bias of the biasing member, and
• wherein the valve allows fluid communication between the first port and the second port when in the first position and wherein the valve allows fluid communication between the second port and the third port when in the second position.
