Abstract of the Disclosure A feathering valve system for modulating the fluid inflow to a selected one of first and second chambers of a moveable biased assembly. A controller is electrically coupled to a first and second solenoid operated pilot valve assemblies for selectively (1) maintaining the pilot valve assemblies in a valve closed state without bleed flow through the pilot orifices or (2) supplying a predetermined value electrical signal to either, but not both, of the valve assemblies for actuating one of the assemblies to an open position related to the valve assembly to a respective chamber whereby the movable assembly moves to a position which is a function of the actuating signal value.
