Abstract: A flow control device in which a flapper is continuously biased to the closed position by a leaf spring that may have a plurality of fingers. The same valve includes a shutoff mechanism allowing the user to adjust forward flow through the valve or shut it off entirely. The leaf spring is made to include polyoxymethylene.

Abstract: This invention relates to a dual bed cathodic protection system with automatic controls and method of use utilizing an impressed cathodic protection anode assembly powered through a solar power supply in conjunction with a sacrificial cathodic protection anode assembly which is known in the prior art to use a corrosion element to emit the necessary electrical current to protect a structure assembly from the effects of corrosion. The dual bed cathodic protection system with automatic controls includes 1) a solar power supply to receive sun power from a solar panel; 2) a ground bed assembly which may either be a deep well or surface type; 3) a system automatic control assembly operable to control selected use of either an impressed or sacrificial protection anode assembly; and 4) a protected structure buried within the ground to receive an electrical current to prevent corrosion thereto.
