ELECTROHYDRAULIC ACTUATORS

TORQUE MOMENT: from 4000 to 325000 Nm.

TANK VOLUME: 75 – 225 litres

MOTOR PUMP GROUP:

  • Pump type External gear pump
  • Nominal motor power 4 kW
  • pump capacity 6,1 l/min
  • operating pressure (maximum) 220 bar

RECOMMENDED POWER OIL: Lukoil Geyser M3

PROTECTIVE CLASS: IP66

DEGREE OF EXPLOSION PROTECTION: 1ExdIIBT3

HYDRAULIC ACCUMULATORS: piston accumulators 50 litres, gas bottle – 50 litres, Charging pressure is up to 190 bar, the amount varies depending on the ball valve nominal diameter.

Electrohydraulic actuators are specifically designed to ensure efficient and reliable operation of shut-off cocks in difficult operating conditions

APPLICATION: for manual and remote control of on-off valves with diameters from 300 to 1400 on pipelines and process installations.

CLIMATIC MODIFICATION: according to GOST 15150: «УХЛ» (areas with temperate and cold climates and ambient temperatures ranging from -60°C to +40°C).

ELECTRIC MOTOR PROTECTIVE CLASS: in explosion-protected low-temperature version has IP66 protection class, as well as all other equipment included in the module.

CONTROL MODES: automatic, unattended (manual back-up by means of a separate manual pump).

It provides autonomous operation with no power supply (accumulated battery energy). Operating mechanism and number of pneumohydraulic accumulators varies depending on the conditional passage of the ball valve.

The items are environmentally friendly, as they do not use natural gas.
The electrohydraulic actuator complies with the proprietary standard of Gazprom 2-4.1-212 and meets the technical requirements of the valve manufacturers.

It has a higher efficiency than pneumatic actuators.
