Abstract

A valve assembly for controlling flow of gases and liquids includes a valve housing having a first end wall, a second end, and a peripheral wall such that a lumen is defined within the valve housing. Each of the first and second ends has an opening extending therethrough. A pipe extends into the lumen and is integrally coupled to the valve housing. The pipe has a free end positioned within the valve housing. A valve is positioned in the valve housing and is adapted for selectively opening and closing the opening in the first end wall. A resiliently expandable jacket is in fluid communication with the free end of the pipe. A pressurized fluid may be placed in communication with the pipe such that the resiliently expandable jacket expands to selectively position the valve in an open or closed position with respect to the opening in the first end wall.
