Pressure compensated control valves

摘要

A multiple section control valve bank is provided having a control valve section and an inlet section operatively connected to provide smooth proportional metering control over a wide band of operating pressures while simultaneously metering the operation of two or more fluid actuated devices from a single fluid source. This is accomplished by providing metering and logic elements in the control valve section connected to a signal chamber in the inlet section to vary the flow of fluid through the inlet section to the control section in accordance with signals from the meter and logic elements.
