The pilot spool initiates, followed by the main spool's opening due to pressure differences, enabling efficient overflow from P to T. Capable of handling back pressure with exceptional opening and closing rates, this valve is ideal for high-pressure, large-flow hydraulic systems.Specifications1. Rated pressure: 210 bar2.
