The valve assembly as in claim 3, wherein said sealing member is a ball movably received with an inner race defined by said plurality of second channels, said ball being spring biased against said actuating tip in a direction opposite to the direction from the first position to the second position. 6. The valve assembly as in claim 5, wherein said ball is spring biased by a spring and a spring retaining member disposed in said third port. 7. The valve assembly as in claim 3, wherein said sealing member is ball movably received within an inner race defined by said plurality of second channels, said ball being adapted to be moved by said actuating tip. 8. The valve assembly as in claim 1, wherein said first port comprises a pair of control ports, and said second port comprises a pair of exhaust ports, and said third port is a supply port. 9. The valve assembly as in claim 1, wherein an axis of said central opening is aligned with an axis of said movable element and the axis upon which the plunger moves. 10. The valve assembly as in claim 9, wherein said movable element is not fixedly secured to the plunger. 11. The valve assembly as in claim 10, wherein said movable element comprises a head portion, a main body portion and an actuating tip, wherein said head portion seals said plurality of first channels from said second port when the plunger is in the second position and said actuating tip enables fluid communication between said plurality of first channels and said plurality of second channels. 12. The valve assembly as in claim 11, wherein said actuating tip moves a sealing member away from said reduced opening thereby enabling fluid communication between said plurality of first channels and said plurality of second channels via said reduced opening, said sealing member being spring biased in a direction opposite to the movement of the movable element when the plunger moves from the first position to the second position. 13. The valve assembly as in claim 1, wherein said first port comprises a pair of control ports orthogonally positioned with respect to said central opening and said second port comprises a pair of exhaust ports orthogonally positioned with respect to said pair of control ports, and said third port is a supply port. 14. The valve assembly as in claim 13, wherein said movable element comprises a head portion, a main body portion and an actuating tip andfluid communication is enabled by a space defined between said head portion and a portion of said housing when the plunger is in the first position. 15. The valve assembly as in claim 14, wherein said head portion seals said plurality of first channels from said pair of exhaust ports when the plunger is in the second position and said actuating tip enables fluid communication between said plurality of first channels and said plurality of second channels. 16. The valve assembly as in claim 15, wherein an axis of said central opening is aligned with an axis of said movable element and the axis upon which the plunger moves. 17. The valve assembly as in claim 16, wherein said movable element is not fixedly secured to the plunger. 18. The valve assembly as in claim 16, wherein said head portion travels through a primary plate of the solenoid when the plunger is moved from the first position to the second position. 19. The valve assembly as in claim 1, wherein said plurality of first channels are disposed on either said housing or a portion of said movable element. 20. A three port-two way valve assembly, comprising:a solenoid for actuating a plunger between a first position and a second position wherein movement of said plunger from said first position to said second position manipulates an element of the valve assembly wherein movement of said element closes a first fluid path and opens a second fluid path, said first fluid path being defined by;a first port in the valve assembly,a plurality of first openings in fluid communication with said first port, said plurality of first openings defining a race for a portion of said element to move within,and a second port in fluid communication with said plurality of first openings when said plunger is in said first position; andsaid second fluid path being defined by;a third port in the valve assembly,a plurality of second openings in fluid communication with said third port, said plurality of second openings defining a race for a sealing member movably disposed in said race, andan opening in fluid communication with said plurality of first openings and said plurality of second openings when said plunger is in said second position. 21. The valve assembly as in claim 20, wherein said element comprises a head portion, a main body portion and an actuating tip, wherein said head portion seals said plurality of first openings from said second port when the plunger is in the second position and said actuating tip enables fluid communication between said plurality of first openings and said plurality of second openings by moving a sealing member of said opening away from a sealing position, said sealing member being biased into said sealing position. 22.
