Y&F 8277 SERIES
INLET GUIDE VANE ACTUATOR ASSEMBLY PB-010 Rev. A
FEATURES
APPLICATIONS The Y&F 8277 Series Inlet Guide Vane Actuators are used for Inlet Guide Vane (IGV) positioning and control of industrial or utility large frame gas turbines. The 8277 Series actuators will force the IGV’s closed in the event of a turbine trip.
DESCRIPTION OF OPERATION The actuator incorporates a hydraulic trip mechanism. The trip valve mechanism consists of a two-position directional control spool valve in series between the servo valve and the hydraulic cylinder. The porting of the directional control valve is such that, in the trip position, the servo valve is isolated from the cylinder and hydraulic fluid is diected to extend the actuator, closing the IGV. The trip valve connects the servo valve ports to the cylinder ports, in the run position. For Details, contact Sherman International Private LTD (www.sherman-india.com) or Young & Franklin, Inc. (www.yf.com).
