Abstract
An electrohydraulic valve has a valve body with a longitudinal bore and a cylindrical exterior surface. An annular recess extends around the cylindrical exterior surface and the first port extends from the recess to the bore. A filter is formed by a plate that has a plurality of perforations and which is wrapped around valve body in the recess. The plate has a first end section at which a first tab is created and a second end section overlapping the first end section with a slot through which the first tab extends to secure the first and second end sections together. A spool is slideable into different positions within the bore of the valve body to selectively connect and disconnect the first port and a second. An actuator is operably coupled to move the spool into different positions within the bore.
