Enovid was first marketed in the U.S. in 1957 not for birth control but to help with disturbances of menstruation (see Enovid brochure above). The U.S. Food & Drug Administration mandated a warning on the label that it would prevent ovulation. And women quickly learned that this pill would prevent pregnancy.
(December 2009). Solenoid valves. A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports.imilarly, if the valve is closed when the solenoid is not energized, then the valve is termed normally closed. There are also 3-way and more complicated designs. A 3-way valve has 3 ports; it connects one port to either of the two other ports (typically a supply port and an exhaust port).
