Question

A(n) ____________________ valve operates similarly to a direct-acting sequence valve except that it has an external pilot line that can sense pressure in another section of the system rather than at the inlet port.

    Answer:

    A remote controlled (or externally piloted) sequence valve

    Explanation:

    First of all, a sequence valve  is a pressure-operated valve that opens at an adjustable set pressure.

    Sequence valves can be internally piloted or externally piloted.

    • Internally piloted sequence valves are known as direct-acting sequence valve. This means that the pressure change they sense is from their main inlet valve.
    • Externally piloted sequence valves have a pilot line in which the pilot signal to open the valve is from a source other than the line feeding it.

    External pilot-operated sequence valves can be used to open and allow flow when a remote operation reaches a certain predetermined pressure.
