Publication number: 20180058592Abstract: Insert elements that may be positioned within a high pressure plug valve. The elements have two or more recessed grooves formed around the fluid opening of the elements. The grooves are spaced from one another. A seal is placed in one and only one of the grooves. As wear occurs, the seal is relocated to one of the other grooves. Instead of a series of spaced grooves in a single insert element, a kit may be formed from two or more otherwise identical insert elements, each with a single recessed groove at a different position around the fluid opening.Type: ApplicationFiled: August 24, 2017Publication date: March 1, 2018Inventor: Kelcy Jake Foster

Publication number: 20180058594Abstract: Provided is a pressure equalizing device for facilitating drug reconstitution in a closed system. The pressure equalizing device includes a container for attachment to a receptacle, to permit pressure equalization between the container and the receptacle. The container includes a first chamber and a second chamber. The device further includes a vent channel extending between the first chamber and a distal opening of the vent channel. In accordance with the invention, when the receptacle is connected to the pressure equalizing device, the vent channel establishes direct fluid communication between the first chamber and the receptacle. Additionally, a longitudinal axis of the pressure equalizing device is configured to be aligned with or parallel to a longitudinal axis of the receptacle when the pressure equalizing device is attached to the receptacle.Type: ApplicationFiled: October 18, 2017Publication date: March 1, 2018Inventor: Alexander Cederschiöld
