  • Technical Feature

    OPERATION:

    These unbalanced, vent-to-open logic valves are 2-way switching elements that are
    spring-biased closed and incorporate an integral shuttle so that the higher of pressures
    at either port
    or port can be used as a pilot source. With port blocked, the valve
    is held in the closed position by the spring force. With port
    vented, the valve will open
    provided there is sufficient pressure to overcome the spring force. The force generated at
    port
    , plus the spring force, must be greater than the sum of the forces acting at port
    and port for the valve to remain closed. NOTE: The pilot area (port ) is 1.8 times the
    area at port
    and 2.25 times the area at port .
