20100024904 | LOW EMISSION FLUID TRANSFER DEVICE - 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. | 02-04-2010 |
20100078084 | VALVE ASSEMBLY - A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore. | 04-01-2010 |

20140260603 | FLOAT GAUGE ASSEMBLY FOR STORAGE TANKS - 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. | 09-18-2014 |
20140261801 | DOUBLE FLANGED OFF-SET VALVE ASSEMBLY - 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. | 09-18-2014 |
20140261817 | VALVE ASSEMBLY INCLUDING PRESSURE RELIEF MECHANISM - 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. | 09-18-2014 |
