Abstract
A valve for controlling fluid flow from an inlet of a pipe fitting to at least one outlet of the pipe fitting at an angle to the inlet. The pipe fitting includes an inner collapsible bellows fixed at a position opposite the inlet. The bellows has a support annulus at the other end adjacent the inlet, whereby, in a closed position, the bellows prevents fluid flow from the inlet to the at least one outlet as the fluid is trapped within the bellows. In an open position, the fluid can flow from the inlet to the at least one outlet when the bellows is collapsed.
