Abstract
A fluid control valve includes a cover portion having a first channel and a body portion having a second channel. Inner surfaces of the cover and the body portion define a chamber that includes an inlet and an outlet in communication with the chamber. The fluid control valve also includes a diaphragm disposed between the cover portion and the body portion. The diaphragm has a flexible member that is disposed within the chamber for controlling communication between the inlet and the outlet and a lip member circumscribing the flexible member. When the cover portion and the body portion are joined, the first channel and the second channel define a cavity that circumscribes the chamber and the cavity is configured such that each channel receives a portion of the lip member and pinches the lip member to seal the fluid control valve and hold the diaphragm.
