<p>VALVE ASSEMBLY A low restriction multiple outlet valve includes a housing having an interior chamber with an inlet opening thereinto, at least two outlets, and a flow directing member. The flow directing member snugly rotates about a portion of the chamber on an axis. The flow directing member also includes at least one aperture therethrough which is spaced from the axis and which is selectively positionable so as to allow flow communication between the inlet and a selected outlet. Preferably, the flow directing member is hemispherical in shape and includes two apertures spaced 90 degrees to each other relative to the axis and the housing includes a pair of outlets spaced 180 degrees from each other relative to the axis. In addition, the valve is normally utilized in conjunction with at least one pressure relief mechanism such as a rupture disc associated with one of the outlets thereof. The valve is normally positioned so as to flow communicate the inlet thereof with the relief device. The flow directing member is manually or automatically rotatable when pressure has damaged the relief device to flow communicate the inlet with the other outlet so as to allow repair of the damaged device. In another embodiment, the valve may have a plurality of outlets while the flow directing member may have one or more apertures so as to allow flow from an inlet to any of many outlets or alternatively, flow from several inlets to respective outlets.</p> |
