Abstract
A diaphragm operated valve including a valve housing having a passage extending therethrough with an inlet and an outlet and a cavity communicating with the passage. A diaphragm extends across the cavity to define a control chamber on one side of the diaphragm. The other side of the diaphragm communicates with the passage. A passageway in the valve housing leads to the control chamber so that the pressure in the control chamber can be varied. A diaphragm support having an opening therein is mounted in the cavity to support the diaphragm, and a vlave element is pivotally mounted within the valve housing for cooperation with the valve seat. The valve seat forms an acute angle with the axis of the passage through the valve housing to minimize pressure losses.
