| 20150369391 | RETRACTABLE HANDLE ASSEMBLY, VALVE USING THE SAME AND INTERMEDIATE BULK CONTAINER - The present invention discloses a retractable handle assembly, a valve using same and IBC. The retractable handle assembly is used in a valve of IBC. The valve comprises a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle can be rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. In the handle assembly of the present invention, the handle can be switched between a deployed state and a retracted state. When the handle is in the retracted state, the space occupied by the handle is quite small, and thus, the handle will not produce bad influence when wielding the valve to the liner bag of IBC. Moreover, after the handle is retracted it will not be easily damaged. | 12-24-2015 |

The rotatable positioning element comprises a curved outer portion arranged in an associated bearing formed in the support member. | 04-14-2011 |
| 20130126767 | TAP WITH A LOCKING PIN - The present invention is directed to a tap handle assembly for positioning about an installed tap body that includes an outwardly extending spindle. The tap handle assembly has a handle body means that has a body aperture and engagement means for engaging an outer end of the spindle, a pin positionable and moveable within the body aperture, and a biasing means to bias the position of the pin within the body aperture. When the tap handle assembly is assembled with the tap body, the pin is biased to the tap body to substantially prevent the movement of the spindle and to restrict the flow from the tap. | 05-23-2013 |

| 20100243930 | MANUAL VALVE OPERATORS HAVING A LOCKOUT DEVICE - Manual valve operators having a locking device are described. An example manual operator includes a lever rotatably coupled to a locking plate and has a handle that pivots between a first position to prevent rotation of the lever relative to the locking plate and a second position to enable rotation of the lever relative to the locking plate. A lockout member is removably coupled to the handle. The handle has an aperture to receive at least a portion of the lockout member. The lockout member engages a portion of the lever to prevent the handle from pivoting between the first and second positions to prevent rotation of the lever relative to the locking plate when the lockout member is coupled to the handle. | 09-30-2010 |

| 20120241655 | Ergonomic Pneumatic Deadman Valve - A lever actuated pneumatic deadman valve for use in connection with pneumatic blasting equipment is ergonomically designed to reduce fatigue and strain on the operator. The valve is shaped to fit comfortably in the hand of the operator, with a spring biased lever hinged for action to fit the natural movement of the hand. A detent button is sized and positioned for easily accommodating single-handed operation. Another important feature of the deadman valve is the reconfiguration of the valve cartridge with an offset port to produce a cyclonic flow around the spool for reducing the wear on the spool. | 09-27-2012 |

| 20150369390 | Handle for Valve Assembly - A handle assembly is provided for an outlet valve of a tank car wherein the outlet valve has a valve stem rotatable about an axis and is operative to open and close the outlet valve. The handle assembly includes a valve handle for manually opening the outlet valve, a rotatable shaft coupled to the handle, and a coupling coupled to the outlet valve and selectively coupleable to the shaft. A valve rotation control structure includes a first movement control component on one of the coupling and the shaft. The valve rotation control structure is configured to permit the coupling or shaft to move parallel to the axis of the valve stem between a first locked position and a second rotatable position and to rotate about the axis of the valve stem between a first valve closed position and a second valve open position at the second rotatable position. | 12-24-2015 |

| 20090242811 | WATER CONTROL VALVE CORE WITH A SEGMENTED LOCKING FUNCTION - The present invention provides a water control valve core with a segmented locking function. The invention includes a valve casing, a brake unit, and a water control element. A bottom plate under the tube portion of the seat of the brake unit is placed within the hold tank of the valve casing. A driven portion penetrates the bottom plate. The fixed valve, free valve and driving seat of the water control element are arranged within the hold tank of the valve casing. An upper locking portion is assembled under the bottom plate of the seat of the brake unit; and a collapsible lower locking unit is individually manufactured and then assembled onto the locating portion at top of the driving seat of the water control element. The lower locking unit could be interlocked with the upper locking portion. | 10-01-2009 |
