Electro-Hydraulic Servo Regulator "ROTAS-L"

Electro-Hydraulic Servo Regulator "ROTAS-L"
Electro-Hydraulic Servo Regulator "ROTAS-L"
  • High power pump control system which controls the outlet flow of high pressure, and large capacity "L-series" pumps by means of electric signals.
responsibility step response 0.3s (0°→27°)
frequency response 3Hz (±12.5°,-3dB)
hysteresis 1% (less than 0.5°)
linearity <2%

Electro-Hydraulic Servo Regulator "ILIS"

Electro-Hydraulic Servo Regulator "ILIS"

The electric control pump K3VG/K7VG with electrohydraulic servo regulator ''ILIS'' delivers flow accurately according to the pilot voltage signal. ILIS has succeeded the advantage of the ROTAS wellreputed excellent reliability, and has further improved accurate and highly responsive controllability by the latest control technology.
