Abstract: A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve and a pilot valve. An actuator controls both the main valve and the pilot valve. A cam plate interconnects the actuator and the valve assembly. The cam plate provides a quick acting shutoff to quickly move the valve assembly to the closed position. A pivotal and rotatable connector couples the transfer device to the dry break coupler. A lock is integrated with the actuator to lock the valve assembly in the closed position.

Abstract: A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve moveable between a closed-main valve position and an open-main valve position in response to movement of an actuator and a pilot valve moveable between a closed-pilot valve position and an open-pilot valve position in response to movement of the actuator. A configuration of the coupler and the transfer device is coupled together, the coupler valve being in the closed-coupler valve position and the main valve being in the closed-main valve position. A space between a face of the main valve and a face of the coupler valve is minimized to reduce fluid emissions upon uncoupling the transfer device from the coupler.

Abstract: A method of documenting installation of a fluid handling device in a fluid flow system using a form and an identification device. The identification device has a first portion with first identification information and a second portion with second identification information. The method comprises installing the fluid handling device in the fluid flow system. The method further comprises checking for leaks associated with the fluid handling device installed in the fluid flow system. The second portion of the identification device is separated from the fluid handling device while the first portion of the identification device remains coupled to the fluid handling device after checking for leaks. The second portion of the identification device is then affixed to the form.

Abstract: A fluid connector having a longitudinal axis and selective open and closed conditions, includes an elongate conduit member extending along the longitudinal axis, an annular collar disposed about and having axial movement relative to the conduit member between the connector open and closed conditions, and a plurality of split nut members circumferentially distributed about the conduit member and having axial movement relative to the collar between the connector open and closed conditions. The plurality of split nut members and the collar are jointly rotatably about the longitudinal axis, and each split nut member has a distal end defining a threaded nut segment. The split nut member distal ends in the connector closed condition are constrained by the collar against radially separating movement relative to the longitudinal axis and cooperatively define a nut configured to threadedly engage a mating fluid fitting.

Abstract: A valve assembly for mounting a pump to a storage tank of a vehicle includes an upper flange, a lower flange, and a wall extending axially between the upper flange and the lower flange, the lower flange being offset by the wall relative to the upper flange to facilitate installation of the pump on the vehicle.

Abstract: A valve assembly includes a housing having a first chamber, a second chamber, a valve seat disposed between the first chamber and the second chamber, a valve head disposed in the housing and moveable relative to the housing, a valve stem operatively coupled to the valve head for moving the valve head between the open and closed positions, and a pressure relief mechanism including a plug coupled to the valve stem and extending along a plug axis in the bore of the valve head moveable relative to the valve head from a sealed position preventing fluid communication through the bore to an unsealed position allowing fluid communication through the bore for relieving pressure differences between the first chamber and the second chamber when the valve head is in the closed position.

Abstract: A pressure regulator includes a housing having an upper housing portion and a lower housing portion, the lower housing portion defining an annular recess and the upper housing portion having a bottom surface, an annular protrusion extending from the bottom surface, a diaphragm disposed between the upper housing portion and the lower housing portion, the diaphragm including an outer lip having a first thickness, a flexible connecting section connected to the outer lip and having a second thickness smaller than the first thickness, and an annular inner section connected to the flexible connecting section, the outer lip having a bottom surface disposed in the annular recess and a top surface, and the protrusion being pressed into the top surface so that the outer lip seals between the upper housing portion and the lower housing portion.

Abstract: A float gauge assembly for a storage tank having a port with an opening includes a body for attachment to the port of the storage tank and a gauge mountable to the body, the gauge having a gauge face for indicating a level or amount of material present in the storage tank, a float mechanism mounted to the body and cooperating with the gauge, the float mechanism including a float movable relative to the body in an operating position, the float being sized so that the float is unable to be inserted into the storage tank though the opening in the port, and a tube coupled to the float and having a dimension sized for inserting through the opening in the port, and an alignment element configured to rotationally fix the tube to the body when the float is in the operating position so that the gauge face accurately indicates the level of material in the storage tank when mounted to the body.

Abstract: A system for disabling a vehicle carrying a substance in a storage tank includes a holster defining a cavity for receiving a nozzle in fluidic connection to the storage tank when not in use. The holster includes a main body and a bracket. The bracket is affixable to the vehicle and engagable with the main body at a plurality of positions along the main body. The system further includes a sensor for sensing whether the nozzle is received in the holster. The sensor is also in communication with at least one drive element of the vehicle to disable the at least one drive element when the nozzle is not received within the holster.
