A piezo-actuated valve, comprising: a valve body extending along a first axis (A-B) between a first end and a second end, the valve body defining a first opening (222.1) disposed proximate the first end, a second opening (222.2) disposed proximate the second end, a third opening centrally located on the valve body, and a valve cavity disposed between the first opening and the second opening; a tube connected to the third opening and extending from the valve body along a second axis disposed transverse to the first axis; a shuttle valve assembly slidably disposed within the valve body, wherein the shuttle valve is configured to slide between the first end to a first stopper and the second end to a second stopper; a first piezo injector having an injector tip extending through the first opening; and a second piezo injector having an injector tip extending through the second opening; wherein the tube defines a passageway extending between an inlet and an outlet; characterised in that the shuttle valve assembly is movable between: a first position at a first end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening; a second position at the center of the valve body in which an aperture of the shuttle valve assembly is at least partially disposed within the passageway to facilitate fluid flow through the passageway; and a third position at a second end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening. a valve body extending along a first axis (A-B) between a first end and a second end, the valve body defining a first opening (222.1) disposed proximate the first end, a second opening (222.2) disposed proximate the second end, a third opening centrally located on the valve body, and a valve cavity disposed between the first opening and the second opening; a tube connected to the third opening and extending from the valve body along a second axis disposed transverse to the first axis; a shuttle valve assembly slidably disposed within the valve body, wherein the shuttle valve is configured to slide between the first end to a first stopper and the second end to a second stopper; a first piezo injector having an injector tip extending through the first opening; and a second piezo injector having an injector tip extending through the second opening; wherein the tube defines a passageway extending between an inlet and an outlet; characterised in that the shuttle valve assembly is movable between: a first position at a first end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening; a second position at the center of the valve body in which an aperture of the shuttle valve assembly is at least partially disposed within the passageway to facilitate fluid flow through the passageway; and a third position at a second end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening. a first position at a first end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening; a second position at the center of the valve body in which an aperture of the shuttle valve assembly is at least partially disposed within the passageway to facilitate fluid flow through the passageway; and a third position at a second end in which the shuttle valve assembly closes the passageway of the tube extending from the inlet to the outlet, such that the shuttle valve assembly inhibits fluid flow through the passageway of the tube through the third opening.
