Abstract
A multilateral junction comprising a y-block and a port seal member. The y-block comprises a main bore, a lateral bore, and lateral port formed in the y-block. The port seal member is integrated within the main bore and has at least one of an opened, closed, and choked position. The multilateral junction also includes one or more gaskets configured to hydraulically isolate the lateral bore when the port seal member is in a closed position. The multilateral junction may further include a controller coupled to the port seal member for performing at least one of an opening, closing, and choking operation on the port seal member. The y-block is a single, machined object with the main bore and the lateral bore formed therein. The multilateral junction is useful in applications that require pressure tight seals and minimal restriction of the internal diameter of a main bore.
