"CJ" indicates the specific spool metering characteristic (e.g., linear or modified linear). Center Position M (Closed Center / All Ports Blocked) In the center (neutral) position, all work ports (A, B) and the pressure port (P) are blocked, and the tank port (T) is open. This holds an actuator in place. Solenoid Type Proportional Solenoid Wet armature design Feedback Type Integrated LVDT The spool has a built-in LVDT for closed-loop position control. (This is implied by the "6" series and the H6 amplifier).
