Product Advantages
1. Precise Electronic Proportional Control: EP4 electronic proportional control realizes stepless flow and pressure adjustment, stable output, low hysteresis and highly responsive action, ensuring smooth equipment operation without impact.
2. Integrated Closed‑circuit Design: Built‑in 15cc charge pump, pressure relief valve and check valve, compact structure, easy system matching, fewer pipeline accessories and lower failure rate.
3. High Pressure & Strong Durability: Designed for heavy‑duty working conditions, with rated pressure up to 400bar, excellent pressure resistance and shock resistance, suitable for long‑term continuous operation.
4. Stable Bidirectional Variable Drive: Supports bidirectional oil supply and reversible rotation, realizes flexible forward, reverse and stepless speed regulation of hydraulic travel system.
5. Strong Environmental Adaptability: Optimized mechanical structure with excellent vibration and corrosion resistance, adaptable to harsh working environments such as dust, mud and variable temperature.
