1)Instruction:

  The unloading valve and ZLF25A11 Priority-based flow enlarge valve support the use of larger valve,that allows excess oil confluence to working system,to meet the low loaders and other construction machinery with high flow low pressure and low flow and high pressure operation conditions.

2)Main Technical Parameters:

  Nominal pressure: 160 bar

  Nominal flow:160L/min

  Pressure ratio≥98%
