A valve is provided including a first valve member and a second valve member. The first valve member includes a first step and a first orifice adjacent the first step. The second valve member includes a second step and a second orifice adjacent the second step. The second valve member is movable relative to the first valve member between an open position, in which the first orifice is fluidly connected the second orifice, and a closed position, in which the first orifice is substantially fluidly disconnected from the second orifice. The first and second steps are fluidly connected to the second orifice and substantially fluidly disconnected from the first orifice when the second valve member is in the closed position, and the first and second steps are fluidly connected to the first and second orifices when the second valve member is in the open position.

1. A valve comprising: a valve body;several first valve members, each including a first step and each including a first orifice adjacent the respective first step and configured within and fixed relative to the valve body; andseveral second valve members, each including a second step and a second orifice adjacent the respective second step configured within and movable relative to the valve body, the second valve members movable relative to the first valve members between open positions, in which the first orifices are fluidly connected with the second orifices, and a closed position, in which the first orifices are substantially fluidly disconnected from the second orifices, wherein the first and second steps are fluidly connected to a respective first orifice and a respective second orifice and substantially fluidly disconnected from the remaining orifices when the second valve members are in the closed position, and the first and second steps are fluidly connected to the first and second orifices when the respective second valve member is in the open position;wherein the first valve members define a portion of a plenum;wherein the first orifices are fluidly connected to the plenum; andwherein the plenum is fluidly connected to a plurality of valves. 2. The valve of claim 1, wherein the first and second steps at least partially define a fluid pathway between the first and second orifices when the second valve members are in the open position. 3. The valve of claim 1, further comprising a biasing member in communication with the second valve members, the biasing member urging the second valve members toward the closed position. 4. The valve of claim 3, wherein the first steps are positioned on a side of the respective first orifice furthest away from the biasing member and facing the second steps, and the second steps are located on a side of the first orifices nearest the biasing member when the second valve members are in the closed position. 5. The valve of claim 3, wherein the first steps are positioned on a side of the first orifices closest to the biasing member and the second steps are located on a side of the first orifices furthest away from the biasing member when the second valve members are in the closed position. 6. The valve of claim 3, wherein the second steps are positioned on a side of the second orifices furthest away from the biasing member and the first steps are located on a side of the second orifices nearest the biasing member when the second valve members are in the closed position. 7. The valve of claim 3, wherein the second steps are positioned on a side of the second orifices closest to the biasing member and the first steps are located on a side of the second orifices furthest away from the biasing member when the second valve members are in the closed position. 8. A hydraulic valve manifold comprising: at least two valve bodies interconnected to form a mainstage manifold, each valve body comprising:a plurality of first valve members, each including a first step and a respective first orifice adjacent the first steps configured within and fixed relative to the valve body, anda plurality of second valve members, each including a second step and a respective second orifice adjacent the second steps configured within and movable relative to the valve body, the second valve members movable relative to the first valve members between open positions, in which the first orifices are fluidly connected with the second orifices, and a closed position, in which the first orifices are substantially fluidly disconnected from the second orifices, wherein the first and second steps are fluidly connected to a respective first orifice and a respective second orifice and substantially fluidly disconnected from the remaining orifices when the second valve members are in the closed position, and the first and second steps are fluidly connected to the first and second orifices when the respective second valve member is in the open position;wherein each of the first valve members defines a portion of a plenum;wherein the plenum extends between and is fluidly connected to the first orifice of each of the at least two valve bodies; andwherein the mainstage manifold is configured to fluidly control at least a first hydraulic load and a second hydraulic load. 9. The hydraulic valve manifold of claim 8, wherein the first hydraulic load includes a first variable flow and a first predetermined pressure, and wherein the second hydraulic load includes a second variable flow and a second predetermined pressure, the second variable flow is at least one of the same and different than the first variable flow and the second predetermined pressure is at least one of the same and different than the first predetermined pressure. 10. The hydraulic valve manifold of claim 8, wherein movement of the second valve members to the open position fluidly connects the first orifices with the second orifices. 11. The hydraulic valve manifold of claim 8, wherein movement of the second valve members to the closed position substantially fluidly disconnects the first orifices from the second orifices. 12. The hydraulic valve manifold of claim 8, wherein the first and second steps at least partially define a fluid pathway between the first and second orifices when the second valve members are in the open position. 13. The hydraulic valve manifold of claim 8, further comprising a biasing member in communication with the second valve members, the biasing member urging the second valve members toward the closed position. 14. The hydraulic valve manifold of claim 13, wherein the second steps are positioned on a side of the second orifices closest to the biasing member and the first steps are located on a side of the second orifices furthest away from the biasing member when the second valve members are in the closed position. 15. The hydraulic valve manifold of claim 13, wherein the first steps are positioned on a side of the first orifices furthest away from the biasing member and the second steps are located on a side of the first orifices nearest the biasing member when the second valve members are in the closed position. 16. The hydraulic valve manifold of claim 13, wherein the first steps are positioned on a side of the first orifices closest to the biasing member and the second steps are located on a side of the first orifices furthest away from the biasing member when the second valve members are in the closed position. 17. The hydraulic valve manifold of claim 13, wherein the second steps are positioned on a side of the second orifices furthest away from the biasing member and the first steps are located on a side of the second orifices nearest the biasing member when the second valve members are in the closed position.
