Electro-Hydraulic Power Cylinders - Linear (EHPC)
The Electrohydraulic Power Cylinder (EHPC) provides the force to operate the control valves of a steam turbine. The EHPC is intended for use on mechanical drives or generator driven turbines. The EHPC integrates the actuator, pilot valve, electronic feedback device, final driver and the power cylinder into a single package, eliminating linkage and reducing hydraulic plumbing and wiring.

Current to Pressure Converters (CPC)
The Woodward Current to Pressure Converter (CPC) is designed for positioning steam and fuel valves and/or the associated servos. A 4–20 mA in/out signal is linearly and proportionally converted into a hydraulic output pressure.
