III. Valve Core Function (J-Type 4/3)

Neutral position (both electromagnets de-energized): P→T open (pump unload); A, B ports closed (actuator locked)

Left position (left electromagnet energized): P→A open; B→T open

Right position (right electromagnet energized): P→B open; A→T open

IV. Typical Applications

Machine tools, injection molding machines, die-casting machines, hydraulic stations

Automated production lines, construction machinery

Control of double-acting cylinder requiring neutral position unload + actuator locking
