26. The servo valve of claim 25 wherein the valve is electronically controlled.
27. A method of manufacturing a controlled valve comprising:
providing a valve body having a cavity and a first chamber;
mounting a sleeve between the cavity and the first chamber, wherein the sleeve comprises an inner bore and at least one opening, wherein the inner bore extends from a first end of the sleeve to a second end of the sleeve, wherein the at least one opening extends through the second end of the sleeve, and wherein a portion of the inner bore proximate the second end forms a second chamber;
movably connecting a spool within the inner bore of the sleeve; and
connecting a valve actuator assembly to the spool;
wherein the first chamber is in fluid communication with the second chamber through the at least one opening, and wherein the spool is configured to be movable over at least a portion of the at least one opening to regulate fluid flow therethrough.
