ABSTRACT:
Self-closing breakaway valve assembly of the type having two housings, two rotatable valve members respectively mounted in the housings and spring biased to close, and trigger means holding the valve members open, incorporates a frangible connector frangibly connecting the housings at a desired angular orientation. The frangible connector comprises two clamping rings secured together by frangible screws, the clamping rings defining a peripheral channel which captures two threaded attachment sleeves, which in turn are threaded into the housings to join the housings together. One of the attachment sleeves has a radially outwardly extending flange for turning it during assembly of the housings, such that a desired angular orientation between the housings may be established and maintained during assembly. Axial pins extending from each housing to openings in the clamping ring are used to establish the desired angular orientation.
