1. A valve comprising: an inlet portion configured to couple to a source of a fluid;a body portion in fluidic communication with the inlet portion, the body portion including a flow passage with a wall extending vertically across the flow passage and dividing the flow passage into: a modulated flow path; anda constant flow path located entirely to one side of the modulated flow path wherein the constant flow path has a shape selected from a group consisting of: a D-shape, and a crescent shape; anda butterfly valve located in the modulated flow path, the butterfly valve having a disc fixed to a rotatable shaft, the disc being rotatable with the shaft around a centerline of the shaft, the centerline of the shaft being parallel to the wall. 2. The valve of claim 1, wherein the inlet portion and body portion each have a constant diameter. 3. The valve of claim 1, wherein the inlet portion and the body portion are constructed of a material selected from a group consisting of: metal and plastic. 4. The valve of claim 1, wherein the fluid is air, gas, liquid or combinations thereof. 5. A valve for providing a fluid to an apparatus, the valve comprising: an inlet;a first outlet;a second outlet;a first flow path in fluidic communication with the inlet and the first outlet wherein the first flow path has a shape selected from a group consisting of: a D-shape and a crescent shape;a butterfly valve disposed within the first flow path and configured to control a rate of fluid flow through the first outlet, the butterfly valve including a disc fixed to a rotatable shaft, the disc being rotatable with the shaft around a centerline of the shaft;a second flow path located entirely to one side of the first flow path and in fluidic communication with the inlet and the second outlet, wherein the second flow path is configured to provide a constant flow of fluid to the second outlet; anda separator extending from the inlet to the first and second outlets to define the first flow path and the second flow path in a side-by-side relationship, the separator being parallel to the centerline of the shaft. 6. The valve of claim 5, wherein the inlet is configured to fluidically connect to a source of ram air. 7. The valve of claim 5, wherein the valve has a constant diameter or cross-section. 8. The valve of claim 5, wherein the fluid is air. 9. The valve of claim 5, wherein the separator comprises a vertical wall. 10. The valve of claim 1, wherein the wall extends in a straight line across the flow passage. 11. A valve comprising: an inlet portion configured to couple to a source of a fluid;a body portion in fluidic communication with the inlet portion, the body portion including a flow passage with a wall extending vertically across the flow passage and dividing the flow passage into: a modulated flow path; anda constant flow path located entirely to one side of the modulated flow path, the constant flow path having a shape selected from a group consisting of a D-shape, and a crescent shape; anda butterfly valve located in the modulated flow path, the butterfly valve having a disc rotatable around a centerline of a shaft, the centerline of the shaft being parallel to the wall. 12. The valve of claim 11, wherein the inlet portion and body portion each have a constant diameter. 13. The valve of claim 11, wherein the inlet portion and the body portion are constructed of a material selected from a group consisting of: metal and plastic. 14. The valve of claim 11, wherein the fluid is air, gas, liquid or combinations thereof. 15. A valve for providing a fluid to an apparatus, the valve comprising: an inlet;a first outlet;a second outlet;a first flow path in fluidic communication with the inlet and the first outlet, the first flow path having a shape selected from a group consisting of a D-shape and a crescent shape;a butterfly valve disposed within the first flow path and configured to control a rate of fluid flow through the first outlet, the butterfly valve including a disc rotatable around a centerline of a shaft;a second flow path located entirely to one side of the first flow path and in fluidic communication with the inlet and the second outlet, wherein the second flow path is configured to provide a constant flow of fluid to the second outlet; anda separator extending from the inlet to the first and second outlets to define the first flow path and the second flow path in a side-by-side relationship, the separator being parallel to the centerline of the shaft. 16. The valve of claim 15, wherein the inlet is configured to fluidically connect to a source of ram air. 17. The valve of claim 15, wherein the valve has a constant diameter or cross-section. 18. The valve of claim 15, wherein the separator comprises a vertical wall. 19. The valve of claim 15, wherein the wall extends in a straight line across the flow passage.
