Woodward 13E and 17E Actuators

 Woodward TG-13E and TG-17E Actuators

SPECIFICATIONS

GOVERNOR DRIVE Shaft 1/2" dia. Number 5 Woodruff key (1/8") 

Speed Range The pump is sized to operate over the following ranges: 

1100 to 2400 rpm 

2400 to 4000 rpm 

4000 to 6000 rpm   

Different actuator part numbers are required for different ranges.

Drive Power Requirement 1/3 to 1/2 hp (249 to 373 W) required to turn drive shaft at rated speed

Rotation Clockwise or counterclockwise, as viewed from top of actuator; rotation can be changed by removing four screws and rotating pump housing 180° 

Work Output MAXIMUM WORK CAPACITY OVER FULL GOVERNOR TRAVEL OF 42° IS * FT-LBS. SEE FIGURE 1 FOR RECOMMENDED GOVERNOR OUTPUT TRAVEL. IN SPECIAL APPLICATIONS MIN AND MAX PRIME MOVER STOPS MAY BE OUTSIDE THE GOVERNOR STOPS. * TG-13E 12.2 ft-lbs (16.5 Nxm) * TG-17E 17.5 ft-lbs (23.7 Nxm)   

Output Shaft 0.625-36 serration on both sides of case

Calibration 1° to 3° off minimum shaft position at 20mA and 37° to 39° shaft position at 160 mA 

CONTROL QUALITIES Actuators will meet NEMA D requirements if used with the proper electronic controls 

Time Constant Shaft Driven 0.090 s at 150 psig (1034 kPa) operating pressure

Hysteresis Within 3% of maximum stroke

Linearity Within 0.5%

Temperature Drift Nominally ±2° of output shaft position per 100° 

Operating Temperature 0 to 200 °F (–18 to +93 °C) with proper viscosity oil 

PILOT VALVE Plunger Movement The pilot valve is actuated hydraulically by varying the oil flow from a nozzle. The flapper, which is controlled by the transducer, varies the flow of oil from the nozzle causing a pressure change above the differential power land, forcing it to move. Oil is then directed to or from the power piston, changing the restoring spring forces until the pilot valve is returned to its null position.

Feedback Adjustable 

TRANSDUCER COIL Coil Resistance 30 to 35 Ω at 68 °F (20 °C) 

Maximum Allowable Current 400 mA 

Nominal Input Current Range 20 to 160 mA for one or two actuators operating from one electronic control 

Electrical Connector 4 Pin MIL-STD-1651-14S-2P 

HYDRAULIC SYSTEM Oil Self-contained sump; SAE 10 to 50 is recommended with a viscosity of 100 to 300 to SUS, depending on operating temperature. See Woodward oil manual 25071 for recommended oils. 

Relief Valve Integral part of accumulator and maintains 150 psi (1034 kPa) for the TG-13E and 200 psi (1379 kPa) from the TG-17E 

Capacity 1.75 quarts (1.7 L) 

Filtration Removable oil filter element in cover for all actuators except external hydraulic supply 

External Hydraulic Supply (for unit not requiring a drive) 1 to 4 USgal/min (3.8 to 15 L/min) supply flow to regulate accumulator between 150 and 170 psi (1034 and 1172 kPa). Supply must be filtered to 25 µm (absolute). Actuator is fitted with a –6 filter fitting (70 µm absolute) and a –10 drain fitting.

CONSTRUCTION Case, Pump Housing, & Cover Aluminum 

Weight 16 lb (7 kg) 

Internal Parts Aluminum, mild and/or case-hardened steel 

MOUNTING Attitude Vertical or horizontal (power servo down)
