Proportional Electro-Hydraulic Directional and Flow Control Valves. A two-stage directional/flow valve that uses a proportional reducing valve with two proportional solenoids as its pilot: flow is controlled by converting the input current in the solenoid, and direction is set by which of the two solenoids is energised. Used with a dedicated Yuken power amplifier, it handles actuator speed, acceleration/deceleration and direction in a single valve, simplifying the circuit and cutting cost. Sub-plate mounting, valve size 03. Max operating pressure 25 MPa, rated flow 100 L/min, pilot pressure 1.5–16 MPa, tank port pressure 16 MPa, rated current 800 mA, coil 10Ω. Spool forms 3C2/3C40; meter-in/meter-out (XY); internal/external pilot.
