Hydraulic Equipment

Along with constantly improving performance, industrial machines continue to become increasingly sophisticated. Hydraulic equipment has to meet the challenge of diversifying needs. You may already appreciate the Nachi-Fujikoshi reputation for compact equipment that delivers energy efficiency, safety, and high performance. Our equipment is also constantly refined by our quest for ultimate hydraulics that combine great power with flexible motion control.

VALVE

 
  • Change the clutch, and control the hydraulic pressure of the clutch is used in Automatic Transmission.
  • 3-ways valve for the energy saving
  • Lightest weight and compact

 

 

 

 


 
  • Modular valve withe a switch that opens/closes electric circuits upon sensing a pressure change in hydraulic circuits.
  • Built-in indicator light in DIN connector, which enables a visual check of operation.
  • W type with both A and B port controls results in compact equipment.

 

 


 
  • No drain flow for energy-saving operation.
  • Can achieve highly responsive, high-accuracy switch output.
  • Long life for enhanced reliability
  • With electric trimmer, pressure and hysteresis can be freely changed within adjustment range.
  • Photo coupler electrically isolates switch output from internal circuit, preventing misoperation due to noise.

 

 

  


 
  • High pressure and large capacity

            Maximum working pressure: 25,35 MPa
            Maximum flow: 50 L/min

  • Stacking system and bolt detaching system allows circuits to be configured, changed and added easily and immediately.
  • Compact size for reduced space
  • Decrease noise and Vibration due o reduced pipings
  • Various series and models; G01 size has 58 series and 131 models

 

 

 


 
  • High pressure and large capacity Maximum working pressure: 25,35 MPa Maximum flow: 100 L/min
  • Stacking system and bolt detaching system allows circuits to be configured, changed and added easily and immediately.
  • Compact size for reduced space
  • Decrease noise and vibration due to reduced pipings
  • Various series and models; G03 size has 52 series and 96 models

 

 

 

 

 


 

Load Sensing Valve

 

  Provides all functions required for mini excavator

  • Anti-saturation function
  • Pressure compensation function according to self loaded pressure
  • Cooperative system with engine speed
  • No need for independent pump of swing motor
  • LS control + constant horsepower control
  • Good for straight traveling of wheel motors
  • Various kinds of attached valves
