Disclosed is an exemplary valve having a first valve member that may include at least one orifice, and which is moveable between a first position and a second position, and a second valve member that includes at least one orifice, and which is moveable relative to the first valve member between a first position, in which the at least one orifice of the second valve member is fluidly disconnected from the at least one orifice of the first valve member, and a second position, in which the at least one orifice of the second valve member is fluidly connected to the at least one orifice of the first valve member. The exemplary valve may also include first and second actuators for moving the first and second valve members between their respective first and second positions.

1. A valve comprising: a first valve member including at least one orifice, the first valve member moveable between a first position and a second position;a first actuator operably connected to the first valve member, the first actuator being an electromagnetic actuator and operable for moving the first valve member between its first and second positions; anda second actuator operably connected to the first valve member, the second actuator is a hydro-mechanical actuator and is operable for moving the first valve member between its first and second positions;wherein the hydro-mechanical actuator and then the electromagnetic actuator are operated sequentially, with the hydro-mechanical actuator moving the first valve member to a vicinity of a desired position and the electromagnetic actuator moving the first valve member to the desired position. 2. The valve of claim 1 further comprising: a second valve member including at least one orifice, the second valve member moveable relative to the first valve member between a first position, in which the at least one orifice of the second valve member is fluidly disconnected from the at least one orifice of the first valve member, and a second position, in which the at least one orifice of the second valve member is fluidly connected to the at least one orifice of the first valve member; anda third actuator operably connected to the second valve member, the third actuator is an electromagnetic actuator and is operable for moving the second valve member between its first and second positions. 3. The valve of claim 2 further comprising a fourth actuator operably connected to the second valve member, the fourth actuator is a hydro-mechanical actuator and is operable for moving the second valve member between its first and second positions, wherein the first and second actuators move the first valve member in a direction substantially opposite a direction the third and fourth actuators move the second valve member. 4. The valve of claim 2, wherein the first, second and third actuators operate concurrently to move the first and second valve members between their respective first and second positions, and the first and second actuators move the first valve member in a direction substantially opposite a direction the third actuator moves the second valve member. 5. A valve comprising: a first valve member including at least one orifice, the first valve member moveable between a first position and a second position;a first actuator operably connected to the first valve member, the first actuator being an electromagnetic actuator and operable for moving the first valve member between its first and second positions; anda second actuator operably connected to the first actuator, the second actuator is a hydro-mechanical actuator and is operable for moving at least a portion of the first actuator operably connected to the first valve member between a first position and a second position;wherein the hydro-mechanical actuator and then the electromagnetic actuator are operated sequentially, with the hydro-mechanical actuator moving the first valve member to a vicinity of a desired position and the electromagnetic actuator moving the first valve member to the desired position. 6. The valve of claim 5 further comprising: a second valve member including at least one orifice, the second valve member moveable relative to the first valve member between a first position, in which the at least one orifice of the second valve member is fluidly disconnected from the at least one orifice of the first valve member, and a second position, in which the at least one orifice of the second valve member is fluidly connected to the at least one orifice of the first valve member; anda third actuator operably connected to the second valve member, the third actuator is an electromagnetic actuator and is operable for moving the second valve member between its first and second positions. 7. The valve of claim 6 further comprising a fourth actuator operably connected to the third actuator, the fourth actuator is a hydro-mechanical actuator and is operable for moving at least a portion of the third actuator operably connected to the second valve member between a first position and a second position. 8. The valve of claim 7, wherein the first and second actuators move the first valve member in a direction substantially opposite a direction the third and fourth actuators move the second valve member. 9. The valve of claim 6 further comprising a fourth actuator operably connected to the second valve member, the fourth actuator is a hydro-mechanical actuator and is operable for moving the second valve member between its first and second positions. 10. The valve of claim 6, wherein the first, second and third actuators operate at least substantially concurrently to move the first and second valve members between their respective first and second positions, and the first and second actuators move the first valve member in a direction substantially opposite a direction the third actuator moves the second valve member.
