Notes :
*1.Value when pressure drop volume to P to A and P to B is  P =1.0MPa {10kgf/cm²}.
*2.Indicates maximum throughput volume value between each port.
*3.Indicates differential between the pilot port and tank port, or drain port.
*4.Value when 0.1 second is assumed for the response time from zero to the rated flow volume.
*5.Value when a Nachi-Fujikoshi special amplifier is used.
*6.Response time is typical value for a supply pressure of 14MPa {143kgf/cm²} and fluid temperature of 40°C (kinematic viscosity: 40mm²/s).
