Nachi Solenoid Valve tipe ESD-G01
Kitoma Indonesia - menyediakan Nachi Solenoid Valve tipe ESD-G01
Electro - Hydraulic Proportional Flow and Directional Control Valve
Features Solenoid Valve tipe ESD-G01
- Provides both direction switching and speed control functions.
- Controls direction by supplying an input current into one of the two proportional solenoids and controls flow by changing the input current.
- Remote control and shockless acceleration/deceleration control enables simplification of the hydraulic circuit.
Applications Solenoid Valve tipe ESD-G01
- General industrial machinery including mainly machine tools and forging/forming equipment
- Carrier device requiring shockless function
- Uses that require continuously changing flow

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).
