  • REMOTE & LOCAL PST “PARTIAL STROKE TEST” AND OPERATION CAPABILITY
  • VARIOUS ELECTRIC MOTOR PUMP VOLTAGES AVAILABLE
  • PRESSURE & VOLTAGE ALARMS
  • ELECTRONIC PRESSURE TRANSMITTER (4-20MA)
  • POSITION FEEDBACK-DEVICE (4-20 MA) AND / OR SWITCHES
  • ALL CONTROL SIGNALS AVAILABLE BY 24VDC HARDWIRE CONTACTS AND / OR BY INTEGRATED SOFTWARE SOLUTION
  • LCD DISPLAY FOR EASY CALIBRATION POSITION & DIAGNOSTIC
  • OIL-LEVEL-PROTECTION
  • HYDRAULIC ENERGY STORED IN HIGH PRESSURE COMPACT ACCUMULTORS
  • AUTOMATIC FAIL SAFE IN CASE OF ELECTRIC POWER FAILURE

Engineered combination of actuators and a self-contained power unit to provide operation and control, the self-contained Electro-Hydraulic Actuators EH series are independent from pipeline pressure power source and they do not exhaust any gas to the atmosphere.
