A hydraulic valve comprises a proportional piloted valve that controls pressure and includes means for restricting pilot flow through the pilot flow passage. The means for restricting pilot flow defines a restriction in the pilot flow passage when a movable spool disposed in an axial bore of the body of the valve is in a neutral position. The restriction varies as a function of spool movement such that flow of hydraulic fluid through the pilot flow passage is variably restricted as a function of the position of the spool over its range of travel.

A method of making a solenoid actuator by laser direct metal deposition can comprise heating with a laser an outer surface of a circumferential groove of a solenoid tube blank constructed of a first material to create a heated area and depositing a second material upon the heated area to form a layer of second material. The second material can melt and then cool to thereby bond to the solenoid tube blank. A bore can be defined in the solenoid tube blank such that the bore includes an interior surface having a ring of second material disposed between a pair of portions of first material.
