Valve fitting

An assembly for preventing the unintentional discharge of flowable material from a container, wherein the assembly comprises a valve comprising a housing having an opening through which, in use, the valve controls the flow of flowable material, a flow control element rotatable between an open configuration and a closed configuration, an actuator for moving the flow control element, and a fitting adapted for insertion into the opening of the housing which in use, when inserted into the opening plugs the opening and locks the flow control element in its closed configuration by preventing rotation of the flow control element.

A method of preventing the unintentional discharge of flowable material from a container through a valve, the valve comprising a housing having an opening through which, in use, the valve controls the flow of flowable material;

• a flow control element rotatable between an open configuration and a closed configuration and an actuator for moving the flow control element, wherein the method comprises the steps of inserting a fitting into the opening of the housing and detachably securing the fitting to the housing thereby to plug the opening and lock the flow control element in its closed configuration.

A kit of parts comprising a valve for a container for storing powder, the valve comprising a housing having an opening through which the valve controls the flow of flowable material;

• a flow control element rotatable between an open configuration and a closed configuration and an actuator for moving the flow control element;
• and a fitting adapted for insertion into the opening of the housing which, in use when inserted into the opening, plugs the opening and locks the flow control element in its closed configuration by preventing rotation of the flow control element.

An assembly for preventing the unintentional discharge of flowable material from a container, wherein the assembly comprises a valve comprising a housing having an opening through which the valve controls the flow of flowable material when in use, a flow control element rotatable between an open configuration and a closed configuration, an actuator for moving the flow control element, and a fitting adapted for insertion into the opening of the housing, to plug the opening, wherein the fitting and valve are configured so that the fitting cannot be fully inserted into the opening when the flow control element is in its open configuration.

A fitting for preventing the unintentional flow of flowable material out of a container through a valve, the valve comprising a housing;

• a flow control element rotatable between an open configuration and a closed configuration, and an actuator for moving the flow control element, wherein the fitting is adapted for insertion into the housing which in use locks the flow control element in its closed configuration by preventing rotation of the flow control element, said fitting comprising a cylindrical tube a plate arranged to close one end of the cylindrical tube, a circular groove formed in the plate for receiving a seal, the seal being provided in the circular groove.
