How Does a Diaphragm Valve Work?

The diaphragm valve opens and closes via a turn handle which is connected to a plunger.  The plunger applies pressure to the diaphragm which then flexes up or down to control flow.  Turning the handle clockwise will lower the diaphragm causing flow to decrease while turning the handle counterclockwise raises the diaphragm increasing product flow through the valve.
