ABSTRACT:
A fully draining valve including an upper valve portion and a lower valve portion. The lower valve body has an integral weir, which in conjunction with a resilient diaphragm, defines a fluid passage. The weir axis is sloped from a horizontal plane. A first duct axis is sloped downwardly away from the weir and sloped from the horizontal plane. A second duct axis is sloped downwardly away from the weir and sloped from the horizontal plane. A third duct axis is oriented downwardly away from the weir and substantially parallel to a vertical axis such that substantially all liquid from within the fluid passage drains from the valve by gravity.
