The heat exchanger manifold has a first face defining a first flow inlet and an exhaust outlet, a second face disposed opposite the first face and defining a second flow inlet, a third face extending between the first face and the second face, and a first side and a second side disposed opposite the first side. The first side and the second side each extend between the first face, the second face, and the third face. A first torque motor assembly is mounted to the first side. A second torque motor assembly is mounted to the second side. ## Claims ### Claim 1 A valve system, comprising: a heat exchanger manifold having a first face disposed opposite a second face, a third face extending between distal ends of the first face and the second face, and a first side and a second side disposed opposite the first side, the first side and the second side extending between the first face, the second face, and the third face, the first face defining an exhaust outlet and a first flow inlet that receives a first flow from a first flow source, the second face defining a second flow inlet that receives a second flow from a second flow source; the third face defines a first flow outlet disposed proximate the first side through which a first portion of the first flow exits the valve system and a second flow outlet disposed proximate the second side through which a second portion of the first flow exits the valve system; a first torque motor assembly mounted to the first side; a first valve member that controls the flow of the first portion through the first torque motor and from the first flow inlet to the first flow outlet; and a heat exchanger in the heat exchanger manifold that receives the first fluid flow and cools the first fluid flow using the second fluid flow, delivers the first portion of the first fluid flow to the first torque motor assembly, and directs the second fluid flow towards the exhaust outlet. ### Claim 2 (depends on 1) The valve system of claim 1, wherein the first torque motor assembly is arranged to receive the first portion of the first fluid flow and direct the first portion of the first fluid flow to the first flow outlet. ### Claim 3 (depends on 1) The valve system of claim 1, further comprising: a second torque motor assembly mounted to the second side; and a second valve member that controls the flow of a second portion of the first fluid flow received at the first flow inlet through the second torque motor. ### Claim 4 (depends on 3) The valve system of claim 3, wherein the heat exchanger delivers the second portion of the first fluid flow to the second torque motor assembly. ### Claim 5 (depends on 4) The valve system of claim 4, wherein the second torque motor assembly is arranged to receive the second portion of the first fluid flow and direct the second portion of the first fluid flow to the second flow outlet. ### Claim 6 A valve system, comprising: a heat exchanger disposed within a heat exchanger manifold having a first face defining a first flow inlet and an exhaust outlet, a second face disposed opposite the first face and defining a second flow inlet, a third face extending between the first face and the second face, and a first side and a second side disposed opposite the first side, the first side and the second side extending between the first face, the second face, and the third face; a first torque motor assembly mounted to the first side; a second torque motor assembly mounted to the second side; a first valve member that controls the flow of a first portion of a first fluid flow received at the first flow inlet through the first torque motor; and a second valve member that controls the flow of a second portion of the first fluid flow received at the first flow inlet through the second torque motor. ### Claim 7 (depends on 6) The valve system of claim 6, wherein the third face defines a first flow outlet disposed proximate the first side and a second flow outlet disposed proximate the second side. ### Claim 8 (depends on 7) The valve system of claim 7, wherein the first flow inlet is arranged to receive the first fluid flow at a first temperature from a first flow source and the second flow inlet is arranged to receive a second fluid flow at a second temperature from a second flow source. ### Claim 9 (depends on 8) The valve system of claim 8, wherein the heat exchanger receives the first fluid flow and cools the first fluid flow using the second fluid flow, delivers a first portion of the first fluid flow at a third temperature to the first torque motor assembly, and directs the second fluid flow towards the exhaust outlet. ### Claim 10 (depends on 9) The valve system of claim 9, wherein the heat exchanger receives the first fluid flow and cools the first fluid flow using the second fluid flow, delivers a second portion of the first fluid flow at the third temperature to the second torque motor assembly, and directs the second fluid flow towards the exhaust outlet. ### Claim 11 (depends on 10) The valve system of claim 10, wherein the first torque motor assembly is arranged to receive the first portion of the first fluid flow and direct the first portion of the first fluid flow to the first flow outlet. ### Claim 12 (depends on 10) The valve system of claim 10, wherein the second torque motor assembly is arranged to receive the second portion of the first fluid flow and direct the second portion of the first fluid flow to the second flow outlet.
