ABSTRACT OF THE DISCLOSURE This invention relates to an automatic shut-off valve arrangement for use in fluid transfer systems. In particular, the valve arrangement or assembly may be mounted in a fluid tank or other type of fluid containment zone to automatically shut off flow from a source, when the desired volume of fill is reached. The assembly is for use in automatic or semi-automatic fluid handling systems which include specialized nozzles and coupling systems which eliminate spillage in the process of connection and disconnection of the nozzle and the tank inlet. An automatic shut-off valve arrangement for use in fluid transfer operations which comprises an inlet and an outlet, means for securing the arrangement to a fluid container such that incoming fluid passes through the arrangement when entering the container, the inlet being opened and closed in response to application of external mechanical opening means and/or incoming fluid pressure, and the outlet being normally closed but opened in response to fluid Plow through the arrangement to the container, an ancillary float actuated valve, actuated in response to fluid in the tank reaching a predetermined level, and connected to a bleed passage provided with flow restricting means, and arranged to be in communication with incoming fluid and with operating means of a main valve located in a main valve chamber such that fluid back pressure from the float actuated valve acts upon the operating means of the main valve to close the main valve and the main chamber such that fluid is no longer delivered to the fluid container and the valve assembly is shut off.
