Released Manual 82566 EG-6P/PC, EG-10P/PC Actuator Chapter 1. General Information Description The controlling element of the EG-6 and EG-10 Proportional Actuators is an electrohydraulic transducer which controls oil flow to and from the power piston through the action of a polarized solenoid. The position of the actuator output shaft is proportional to the input current of the solenoid coil controlling the hydraulic pilot-valve plunger. -

C and D in the mating plug. RVDT or minimum-position switch features will require different electrical connections. Actuators designed for use in hazardous environments have conduit boxes permanently attached. EG-6P, EG-10P Actuator (with Compensation) Description Many EG actuators operate with oil supplied directly from the prime mover. -
Page 15: Oil Supply
Released Manual 82566 EG-6P/PC, EG-10P/PC Actuator Oil Supply Clean Supply Dirt in the oil can cause the actuator to malfunction. Many oil pump model actuators are installed with a direct line from either the engine pressure oil system or from the engine oil sump. A 20 to 25 µm absolute filter should be installed in the line from the engine. -
Page 16: Figure 2-1. Oil Viscosity Chart
Released EG-6P/PC, EG-10P/PC Actuator Manual 82566 Adequate drain is important for dependable and stable operation of the oil motor actuator. A minimum of 25 mm (1 inch) ID drain is needed with a continuous drop for up to 3 m (10 ft) from the actuator. Drains longer than 3 m (10 ft) will probably require larger ID pipe. -

Released Manual 82566 EG-6P/PC, EG-10P/PC Actuator Figure 3-1. EG-P Schematic With the unit running on-speed under steady-state conditions, the resulting spring force and the force from the current in the solenoid coils are equal but opposite. This keeps the output shaft at a position to maintain the engine at the required speed. -
Page 24: Voltage Change
Released EG-6P/PC, EG-10P/PC Actuator Manual 82566 The oil motor portion of the actuator operates with a restriction to the pressure oil supply in order to reduce the flow of pressure oil through the oil motor. The orifice is normally fitted internally in the actuator. Some actuators are built without an internal orifice and, in these cases, a separate oil supply and orifice is required. -
