Hydraulic Amplifier

Woodward’s Hydraulic Amplifier is a linear electro-hydraulic actuator designed to operate steam turbine control valves or valve racks. This integrated actuator is intended for use on mechanical-drive or generator-drive steam turbines, and uses a low-pressure hydraulic oil source (typically turbine lube oil) to provide its output shaft force.

The Hydraulic Amplifier’s superb accuracy and resolution make it ideal for steam turbine valve control and related turbine speed and load control.

• Output: linear, 76 mm (3") max stroke, 184 mm (7.25") bore max, 54.5 kN (12,250 lbf) force max
• Input Power: 690 to 3448 kPa (100 to 500 psi), supply oil, 0-200mA - position demand
