PRODUCT DESCRIPTION

All other units in the engine control system must be adjusted and working correctly before operating the synchronizer. While operating the engine to make 

adjustments on the other units, the synchronizer mode switch (user supplied) must be in the OFF position.

Benefits:

 Manual Control knob on governor 

 Pneumatic Direct or reverse. With 21 kPa (3 psi) minimum and 690 kPa (100 psi) 

maximum control air pressure. Ratio of max. to min. air control signal 

pressure must be greater than 2.5 to 1, but less than 10 to 1. Typical 

pneumatic ranges are 21 to 103 kPa (3 to 15 psi) and 69 to 414 kPa (10 to 

60 psi). 0.25 inch (6.4 mm) SAE air connection. 

Bellows Selections (for pneumatic speed setting) 

Bellows 400 mm² (0.62 in²) 194 mm² (0.3 in²) 77 mm² (0.12 in²)

 Max signal pressure 138 kPa (20 psig) 138 to 345 kPa (20 to 50 psig) 345 to 827 kPa (50 to 120 psig) 

 Min signal pressure 21 kPa (3 psig) 48 kPa (7 psig) 69 kPa (10 psig) 

Governor Drive 

 Input Shaft Keyed or 1.125” - 48 serrated. 

 Recommended Speed Range 250 rpm minimum to 1000 rpm maximum. Speeds in excess of 1000 rpm 

are available but require single direction rotation. Oil coolers may also be 

required. Please consult Woodward. 

 Maximum Speed Range The absolute minimum speed is 200 rpm. The absolute maximum speed is 

1600 rpm. 

 Power Requirement Drive power for different types of PG governors will vary depending upon 

speed, internal pump pressure, pump volumetric displacement, pump 

efficiency, and oil viscosity. Contact Woodard if further information is 

required. 

 Rotation Fixed clockwise, fixed counterclockwise, or reversible 

Output 

 Power Cylinder Type and Travel Linear with 1-inch (25 mm) maximum travel or rotary with 30 degrees 

maximum travel. When making connection to engine or turbine linkage, use 

2/3 of the available governor terminal shaft travel between no load and full 

load. Split overtravel at each end so that the governor can shut down the 

prime mover and also give maximum fuel when required. 

 Maximum (stalled) Work Capacity: 

 Governor Operating Oil Work Capacities 

 Pressure Servo 16 J (12 ft-lb) Servo 39 J (29 ft-lb) Servo

 690 kPa (100 psi) (std.) 16 J (12 ft-lb) 39 J (29 ft-lb) 

 1379 kPa (200 psi) 33 J (24 ft-lb) 79 J (58 ft-lb) 

 Usable Work Standard governors, 11 J (8 ft-lb) or 2/3 of maximum work 

Pilot Valve 

 Plunger Movement Balanced between ballhead centrifugal force and speeder-spring force 

 Bushing Rotated integrally with governor drive shaft 

 Porting 4 round or 3 slotted 

Control Characteristics 

 Steady State Speed Band ±0.25% of rated speed (under normal operating conditions) 

 Ballhead Assemblies Solid or spring driven oil damped 

 Operating Temperature Continuous operating temperature is 60 to 93 °C (140 to 200 °F). Consult 

Woodward beyond these limits. Hydraulic pour point must be below lowest 

expected starting temperature. 

Hydraulic System 

 Oil SAE 10 to 50 oil depending on temperature 

 Viscosity 100 to 300 SUS under normal operating conditions 

 Self-Contained Sump Capacity Approximately 1.4 L (1.5 qt) 

 Relief Valves 690 to 1379 kPa (100 to 200 psi) 

 Operating Pressure 690 kPa (100 psi) normal, 1379 kPa (200 psi) optional
