Product profile

Direct Fit, Easy Installation: Designed for a wide range of Hitachi models including EX100-5, EX120-5, EX200-5, EX230-5, EX270-5, ZX200, ZX210-5G, and ZX330-3, as well as other models like 160DLC, 180GLC, 210GLC, and 300GLC. It installs without modification, so you can get back to work fast.

Critical System Overpressure Protection: As the primary safety device for the main hydraulic circuit, the valve releases pressure when it gets too high. When system pressure exceeds the set value, it diverts excess hydraulic fluid to the return line, preventing damage to the main pump, control valve, cylinders, and pipelines from overload.

Smooth and Stable Operation: By keeping hydraulic pressure steady, it helps your machine run smoothly and respond well, even when the load changes. You get consistent performance for digging, lifting, and swinging.
