1. A high temperature gate valve, comprising: a valve body formed to define first and second ports and an exit, each of which has a length-wise dimension greater than a height-wise dimension at respective distal ends of the first and second ports and the exit; anda door, having a length-wise dimension greater than a height-wise dimension, coupled to the valve body to occupy and move around a hinge assembly between positions at which the door prevents fluid communication between one of a proximal section of the first port or a proximal section of the second port and a proximal section of the exit and intermediate positions at which fluid communication between the first and the second ports and the exit is permitted,the respective proximal sections and the respective distal ends of the first port, the second port and the exit being defined at opposite ends of each, andthe length-wise dimensions of the valve body and the door being directed radially away from the hinge assembly and the height-wise dimensions of the valve body and the door being directed along a longitudinal axial of the hinge assembly,wherein the valve body comprises:a first body portion formed to define first and second openings and the exit;a closure, which is sealed to the first body portion at the first opening and formed to define the first port at the first opening; anda second body portion, which is sealed to the first body portion at the second opening and formed to define the second port at the second opening,wherein an angle formed between the lengthwise dimensions of the first port and the exit is greater than an angle formed between the first and second ports. 2. The high temperature gate valve according to claim 1, wherein the closure and the first body portion each comprises complementary mating surfaces. 3. The high temperature gate valve according to claim 2, wherein the complementary mating surfaces are at least one of welded and brazed. 4. The high temperature gate valve according to claim 1, wherein the closure and the second body portion each comprises a seal surface against which the door abuts to prevent fluid communication between the first port and the second port and the exit, respectively, an inner edge of each of the seal surfaces and the door being similarly shaped. 5. The high temperature gate valve according to claim 1, wherein the first port, the second port and the exit are tapered. 6. The high temperature gate valve according to claim 1, wherein the first port, the second port and the exit are rounded at distal ends thereof. 7. The high temperature gate valve according to claim 1, wherein the door is tapered along the length-wise dimension. 8. The high temperature gate valve according to claim 1, wherein the door is rounded at a distal end thereof. 9. The high temperature gate valve according to claim 1, wherein the hinge assembly is integrally formed with the valve body. 10. The high temperature gate valve according to claim 9, wherein the hinge assembly comprises a shaft about which the door pivots and retaining pins to fasten the door to the shaft. 11. The high temperature gate valve according to claim 10, wherein a head of the shaft is operably coupled to an actuator to control movement of the door. 12. A high temperature gate valve, comprising: a valve body formed to define first and second ports and an exit, each of which has a length-wise dimension greater than a height-wise dimension at respective distal ends of the first and second ports and the exit; anda door having a length-wise dimension greater than a height-wise dimension coupled to the valve body to occupy and move around a hinge assembly between positions at which the door prevents fluid communication between one of a proximal section of the first port or a proximal section of the second port and a proximal section of the exit and intermediate positions at which fluid communication between the first and the second ports and the exit is permitted,the respective proximal sections and the respective distal ends of the first port, the second port and the exit being defined at opposite ends of each, andthe length-wise dimensions of the valve body and the door being directed radially away from the hinge assembly and the height-wise dimensions of the valve body and the door being directed along a longitudinal axial of the hinge assembly,wherein the valve body comprises:a first body portion formed to define first and second openings and the exit;a closure, which is sealed to the first body portion at the first opening and formed to define the first port at the first opening; anda second body portion, which is sealed to the first body portion at the second opening and formed to define the second port at the second opening,wherein the second body portion comprises upper and lower walls, bosses protruding from the upper and lower walls and a first shoulder, andthe first body portion comprises upper and lower flaps to sealably abut opposite faces of the upper and lower walls, respectively, mating surfaces to abut the bosses and a second shoulder to abut the first shoulder. 13. The high temperature gate valve according to claim 12, wherein the second body portion is at least one of welded and brazed to the first body portion at least at interfaces between the mating surfaces and the bosses and between the first and second shoulders. 14. A high temperature gate valve, comprising: a valve body, having thickness and length-wise dimensions greater than a height dimension at distal ends of first and second ports and an exit, the valve body being formed to define at least first and second flow paths extending from the distal ends of the first and second ports, respectively, each of which has a common exit at the distal end of the exit;a door, having dimensions complementary to those of the valve body, to occupy and move around a hinge assembly between positions at which the door blocks one of the first or the second flow paths at respective proximal sections of the first and second ports and the exit and intermediate positions at which fluid communication along the first and the second flow paths is permitted; andan actuator operably coupled to the door to control the movement of the door,the respective proximal sections and the respective distal ends of the first port, the second port and the exit being defined at opposite ends of each, andthe length-wise dimensions of the valve body and the door being directed radially away from the hinge assembly and the height dimensions of the valve body and the door being directed along a longitudinal axial of the hinge assembly,wherein the valve body has a substantially trapezoidal shape. 15. The high temperature gate valve according to claim 14, wherein the first flow path is curved and the second flow path is substantially straight. 16. The high temperature gate valve according to claim 14, wherein the door pivots about and is fastened to a shaft of the hinge assembly integrally formed with the valve body.
