FLOW SHARING VALVE

Rated flow:90-300 L/min

Applications:Excavators 1.6-18ton

  • High efficiency
  • Less volume, lighter weight
  • Precise controllability
  • Low pressure drop,less fuel consumption
  • Comfort and coordination

Using environment
Hydraulic fluid Mineral oil (HL, HLP) according to DIN 51524. Other hydraulic fluids, such as HEES (Synthetic Ester) according to VDMA 24568.
Hydraulic fluid temperature range(℃) -20 to +90
Viscosity range ν (mm2/s) 10 to 380
Maximum permissible degree of contamination of the pressure fluid cleanliness class to ISO 4406 (℃) Class 20/18/15, we therefore recommend a filter with a minimum retention rate of β10≥75
(For applications outside above mentioned parameters, please consult our sales dept.)
