  • Three position 270 degree actuator
    Patent number: 11047491
    Abstract: An actuator controls the operation of a valve member to achieve desired flow or no-flow states through different inlet ports of the valve in response to different types of input signals from one or more input sources. In some embodiments, the actuator drives the valve member along a first portion of a travel path to regulate flow through a first inlet port using analog or binary input signal(s) from a first input source, and drives the valve member along a second portion of the travel path to regulate flow through a second inlet port using analog or binary input signal(s) from a second input source. In some embodiments the actuator drives the valve member along the entire travel path to regulate flow through each of the first inlet port and the second inlet port responsive to an analog input signal from a single input source.
