摘要： Multidirectional vent limiting devices for use with fluid regulators are described. In some examples, a vent limiting device includes a housing having an interior surface, a fluid inlet, a fluid outlet, and a first fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. The interior surface includes a first sealing surface that defines a portion of the first fluid passageway. In some examples, the vent limiting device further includes a stem and a poppet. In some examples, the stem is rigidly coupled to the interior surface of the housing. In some examples, the poppet includes a second sealing surface that defines a portion of the first fluid passageway, and a radial bore that defines a second fluid passageway in fluid communication with and located between the fluid inlet and the fluid outlet. In some examples, the poppet is slidable along the stem between an open position and a closed position. In some examples, the second sealing surface contacts the first sealing surface when the poppet is in the closed position to close off the first fluid passageway.

摘要： A system and method for automatically performing start-up and overpressure relief functions in association with a primary fluid carrier such as, for example, a liquid handling pipeline or tank. The system includes a main valve for primarily exhausting air from the system as it fills with a liquid. A start-up pilot device is also provided for exhausting air from the system upon start-up, but prior to the main valve opening. Finally, an overpressure pilot device is provided to relieve overpressure situations during normal operation.
